# Setting core pattern in /proc/sys/kernel/core_pattern requires privileged mode

# Default kernel core pattern for amazonlinux should be: '/cores/core_%e.%p'
# However, we have seen that sometimes for unknown reasons cores are just dumped
# to the current working directory. 
# S0 change working directory to the cores folder to run fluent bit from there.
