[Bug 1907310] Re: initramfs-tools ignores the FRAMEBUFFER option _again_

[Benjamin Drung]

I checked on Ubuntu 23.10: cryptsetup-initramfs sets FRAMEBUFFER=y in
/usr/share/initramfs-tools/conf-hooks.d/cryptsetup

So cryptsetup-initramfs enforces including the framebuffer modules.

Title:
  initramfs-tools ignores the FRAMEBUFFER option _again_

Status in initramfs-tools package in Ubuntu:
  Invalid

Bug description:
  see lp:1561643 for the previous 3-year discussion having resulted in a
  (temporary) fix.

  Currently, running Ubuntu 21.04 Hirsute, I noticed +60MB growth in initrd files again.
  Doing lsinitramfs on these images, I found that they are happily stuffed with i915 and amdgpu modules, as well as with netronome nic firmwares which of course everyone surely needs, making initrd of 73 MB.
  That's with MODULES=dep and FRAMEBUFFER=n in /etc/initramfs-tools/initramfs.conf

  this does not happen with Ubuntu 20.04, with same options in initramfs.conf. 
  On my Focal system, initrd images have size of 12MB, with largest components being .so libraries and lvm executable.

  So, I would conclude that initramfs-tools reintroduced this
  misbehavior after 20.04 release but in some different way. Now trying
  to compare /usr/share/initramfs-tools content between 20.04 and 21.04.
  Probably the title of this bug will need to be changed. As I am not
  allowed to reopen lp:1561643 , I am creating a new bug.
