MODULES=list results in error

[Dan Streetman]

[impact]

setting MODULES=list in /etc/initramfs-tools/initramfs.conf results in an error/warning when running update-initramfs

[test case]

edit initramfs.conf to change MODULES=list and run update-initramfs:

$ grep MODULES /etc/initramfs-tools/initramfs.conf
# MODULES: [ most | netboot | dep | list ]
MODULES=list
$ sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-5.8.0-48-generic
find: ‘/var/tmp/mkinitramfs_Yr04uh/lib/modules/5.8.0-48-generic/kernel’: No such file or directory

[regression potential]

any regression would likely result in an initramfs that did not include the correct/required modules, and/or failure to build a new initramfs

[scope]

this is needed for f and g.

this is not fixed in debian, but is fixed in h and i.

the code in b is different and doesn't include this bug, so this doesn't apply to b.

for debian, MR open:
https://salsa.debian.org/kernel-team/initramfs-tools/-/merge_requests/48

[other info]

this caused some of the 'amd64-*' autopkgtests to fail in h until it was fixed. those autopkgtests don't exist in g and earlier so this was not noticed until now.

This bug was fixed in the package initramfs-tools - 0.136ubuntu6.5

---------------
initramfs-tools (0.136ubuntu6.5) focal; urgency=medium

  * scripts/local-premount/resume:
    - Use readlink -f to correctly handle non-symlink $resume
      (LP: #1876570)
  * hook-functions:
    - when MODULES=list there will be no 'kernel' dir, so don't try
      to find anything there, as it will log an error
      (LP: #1927779)
  * hooks/fsck:
    - don't check PASSNO, always include fsck
      (LP: #1917780)
