a/mkinitrd-1.4.11-x86_64-38.txz:  Rebuilt.
  /boot/remove-orphaned-initrds: this script will remove initrds found in /boot
  if there is no matching kernel version found. This can be run manually or
  added as a cron job to prevent unneeded initrds from filling up /boot.
a/pkgtools-15.1-noarch-13.txz:  Rebuilt.
  /boot/kernel-backup: with the huge kernel gone, this script seeks to fill the
  gap by offering an easy way to make a backup kernel that will be picked up
  by update-grub. It does this by creating entries in the pkgtools database
  that protect a kernel, modules, and optionally an initrd from being removed
  when the kernel-generic package is upgraded. See the script for details.
ap/rpm-4.20.0-x86_64-1.txz:  Upgraded.
d/git-2.47.0-x86_64-1.txz:  Upgraded.
l/python-MarkupSafe-3.0.1-x86_64-1.txz:  Upgraded.
l/python-tomli-w-1.1.0-x86_64-1.txz:  Upgraded.
n/cifs-utils-7.1-x86_64-1.txz:  Upgraded.
n/netatalk-4.0.1-x86_64-1.txz:  Upgraded.

# 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).
