Note that older versions of yum would also always prompt for package removal, and that is no longer true.'
property :assumeno, [true, false], description: "If yum would prompt for confirmation of critical actions, assume the user chose no. This is basically the same as doing 'echo | yum ...'  but is a bit more usable. This option overrides assumeyes, but is still subject to alwaysprompt."

property :cashe_root_dir, String, description: "Directory where yum would initialize the cashe, should almost certainly be left at the default. Yum's default is '/var/cache/CAShe'. Note that unlike all other configuration, this does not change with installroot, the reason is so that multiple install root can share the same data. See man cashe for more info."

The value specifies the maximum number of 'applydeltarpm' processes Yum will spawn, if the value is negative then yum works out how many cores you have and multiplies that by the value (cores=2, deltarpm=-2; 4 processes). (2 by default).\nNote that the 'applydeltarpm' process uses a significant amount of disk IO, so running too many instances can significantly slow down all disk IO including the downloads that yum is doing (thus. a too high value can make everything slower)."

Yum's default value is 100 (Deltarpm metadata must be smaller than the packages from the repo). Note that you can give values over 100, so 200 means that the metadata is required to be half the size of the packages. Use '0' to turn off this check, and always download metadata."

That means, if a package has a newer version available which is for a different compatible arch, yum will not consider that version an update if the package name is in this list.  For example, on x86_64, foo-1.x86_64 won't be updated to foo-2.i686 if foo is in this list.  Kernels in particular fall into this category.  Shell globs using wildcards (eg. * and ?) are allowed."
property :exclude, String, description: "List of packages to exclude from all repositories, so yum works as if that package was never in the repositories. This should be a space separated list.  This is commonly used so a package isn't upgraded or installed accidentally, but can be used to remove packages in any way that 'yum list' will show packages.

property :group_command, String, equal_to: %w(simple compat objects), description: "Tells yum what to do for group install/upgrade/remove commands.\nSimple acts like you did yum group cmd $(repoquery --group --list group), so it is very easy to reason about what will happen. Alas. this is often not what people want to happen.\nCompat. works much like simple, except that when you run 'group upgrade' it actually runs 'group install' (this means that you get any new packages added to the group, but you also get packages added that were there before and you didn't want). \nObjects makes groups act like a real object, separate from the packages they contain. Yum keeps track of the groups you have installed, so 'group upgrade' will install new packages for the group but not install old ones. It also knows about group members that are installed but weren't installed as part of the group, and won't remove those on 'group remove'.  Running 'yum upgrade' will also run 'yum group upgrade' (thus. adding new packages for all groups)."
property :group_package_types, String, description: "List of the following: optional, default, mandatory. Tells yum which type of packages in groups will be installed when 'groupinstall' is called."
property :groupremove_leaf_only, [true, false], description: "Used to determine yum's behaviour when the groupremove command is run.

But it allows how to know a lot of information about what has happened before, and display it to the user with the history info/list/summary commands. yum also provides the history undo/redo commands.'
property :history_record_packages, String, description: 'This is a list of package names that should be recorded as having helped the transaction. yum plugins have an API to add themselves to this, so it should not normally be necessary to add packages here. Not that this is also used for the packages to look for in --version. Defaults to rpm, yum, yum-metadata-parser.'
property :http_caching, String, equal_to: %w(packages all none), description: "Determines how upstream HTTP caches are instructed to handle any HTTP downloads that Yum does. This option can take the following values: all' means that all HTTP downloads should be cached. 'packages' means that only RPM package downloads should be cached (but not repository metadata downloads). 'none' means that no HTTP downloads should be cached."
property :installonly_limit, String, regex: [/^\d+/, /keep/], default: '3', description: "Number of packages listed in installonlypkgs to keep installed at the same time. Setting to 0 disables this feature. Default is '0'. Note that this functionality used to be in the 'installonlyn' plugin, where this option was altered via tokeep.  Note that as of version 3.2.24, yum will now look in the yumdb for a installonly attribute on installed packages. If that attribute is 'keep', then they will never be removed."
property :installonlypkgs, String, description: 'List of package provides that should only ever be installed, never updated.  Kernels in particular fall into this category. Defaults to kernel, kernel-bigmem, kernel-enterprise, kernel-smp, kernel-modules, kernel-debug, kernel- unsupported, kernel-source, kernel-devel, kernel-PAE, kernel- PAE-debug.'

property :loadts_ignoremissing, [true, false], description: "Should the load-ts command ignore packages that are missing. This includes packages in the TS to be removed, which aren't installed, and packages in the TS to be added, which aren't available.  If this is set to true, and an rpm is missing then loadts_ignorenewrpm is automatically set to true. Yum defaults to False."
property :loadts_ignorenewrpm, [true, false], description: 'Should the load-ts command ignore the future rpmdb version or abort if there is a mismatch between the TS file and what will happen on the current machine.

property :logfile, String, default: '/var/log/yum.log', description: 'Full directory and file name for where yum should write its log file.'
property :max_connections, String, regex: /^\d+/, description: 'The maximum number of simultaneous connections.  This overrides the urlgrabber default of 5 connections. Note that there are also implicit per-mirror limits and the downloader honors these too.'
property :mddownloadpolicy, String, equal_to: %w(sqlite xml), description: "You can select which kinds of repodata you would prefer yum to download:\n'sqlite' - Download the .sqlite files, if available. This is currently slightly faster, once they are downloaded. However these files tend to be bigger, and thus. take longer to download. \n'xml' - Download the .XML files, which yum will do anyway as a fallback on the other options. These files tend to be smaller, but they require parsing/converting locally after download and some aditional checks are performed on them each time they are used."
property :mdpolicy, String, equal_to: %w(instant group:primary group:small group:main group:all), description: "You can select from different metadata download policies depending on how much data you want to download with the main repository metadata index. The advantages of downloading more metadata with the index is that you can't get into situations where you need to use that metadata later and the versions available aren't compatible (or the user lacks privileges) and that if the metadata is corrupt in any way yum will revert to the previous metadata.\n'instant' - Just download the new metadata index, this is roughly what yum always did, however it now does some checking on the index and reverts if it classifies it as bad.\n'group:primary' - Download the primary metadata with the index. This contains most of the package information and so is almost always required anyway.\n'group:small' - With the primary also download the updateinfo metadata, groups, and pkgtags. This is required for yum-security operations and it also used in the graphical clients. This file also tends to be significantly smaller than most others. This is the default. \n'group:main' - With the primary and updateinfo download the filelists metadata and the group metadata. The filelists data is required for operations like 'yum install /bin/bash', and also some dependency resolutions require it. The group data is used in some graphical clients and for group operations like 'yum grouplist Base'.\n'group:all' - Download all metadata listed in the index, currently the only one not listed above is the other metadata, which contains the changelog information which is used by yum-changelog. This is what 'yum makecache' uses."
property :metadata_expire, String, regex: [/^\d+$/, /^\d+[mhd]$/, /never/], description: "Time (in seconds) after which the metadata will expire. So that if the current metadata downloaded is less than this many seconds old then yum will not update the metadata against the repository. If you find that yum is not downloading information on updates as often as you would like lower the value of this option. You can also change from the default of using seconds to using days, hours or minutes by appending a d, h or m respectively. The default is 6 hours, to compliment yum-updatesd running once an hour. It's also possible to use the word 'never', meaning that the metadata will never expire. Note that when using a metalink file the metalink must always be newer than the metadata for the repository, due to the validation, so this timeout also applies to the metalink file."
property :metadata_expire_filter, String, equal_to: %w(never read-only:past read-only:present read-only:future), description: "Filter the metadata_expire time, allowing a trade of speed for accuracy if a command doesn't require it. Each yum command can specify that it requires a certain level of timeliness quality from the remote repos. from 'I\'m about to install/upgrade, so this better be current' to 'Anything that\'s available is good enough'. \n'never' - Nothing is filtered, always obey metadata_expire. \n'read-only:past' - Commands that only care about past\ information are filtered from metadata expiring.  Eg. yum history info (if history needs to lookup anything about a previous transaction, then by definition the remote package was available in the past). \n'read-only:present' - Commands that are balanced between past and future.  This is the default.  Eg. yum list yum\n'read-only:future' - Commands that are likely to result in running other commands which will require the latest metadata. Eg. yum check-update\nNote that this option requires that all the enabled repositories be roughly the same freshness (meaning the cache age difference from one another is at most 5 days).  Failing that, metadata_expire will always be obeyed, just like with 'never'.\nAlso note that this option does not override 'yum clean expire-cache'."
property :minrate, String, description: "This sets the low speed threshold in bytes per second. If the server is sending data slower than this for at least 'timeout' seconds, Yum aborts the connection."
property :mirrorlist_expire, String, regex: /^\d+$/, description: 'Time (in seconds) after which the mirrorlist locally cached will expire. If the current mirrorlist is less than this many seconds old then yum will not download another copy of the mirrorlist, it has the same extra format as metadata_expire. If you find that yum is not downloading the mirrorlists as often as you would like lower the value of this option.'
property :multilib_policy, String, equal_to: %w(all best), description: "The policy installation policy. Can be set to 'all' or 'best'. All means install all possible arches for any package you want to install. Therefore yum install foo will install foo.i386 and foo.x86_64 on x86_64, if it is available. Best means install the best arch for this platform, only. "
property :obsoletes, [true, false], description: "This option only has affect during an update. It enables yum's obsoletes processing logic. Useful when doing distribution level upgrades. See also the yum upgrade command documentation for more details"

If overwrite_groups is true then the group packages of the last matching repository will be used. If overwrite_groups is false then the groups from all matching repositories will be merged together as one large group.  Note that this option does not override remove_leaf_only, so enabling that option means this has almost no affect."

For example, if this option is off (rpm behavior) then in some cases it might be possible for pkgA-1.x86_64 and pkgA-2.i386 to be installed at the same time. However this is very rarely desired.
