# This script removes initrds in the /boot directory if there's no kernel
|
|
# in /boot with the same version. This keeps unused initrds from accumulating
|
|
# and filling up the filesystem.
|
|
|
|
# Usage: Run without any options to clean up initrd orphans:
|
|
#
|
|
# ./remove-orphaned-initrds
|
|
#
|
|
# To see what would be removed without actually removing anything:
|
|
#
|
|
# ./remove-orphaned-initrds --dry-run
|
|
#
|
|
# This script is suitable to run as a periodic cron job (perhaps weekly).
