Missing initrd line in grub.cfg after updating kernels

Is this a new report?

Yes

System Info

Void 6.1.4_1 x86_64 GenuineIntel notuptodate rrFFF

Package(s) Affected

linux6.1 linux5.15

Does a report exist for this bug with the project's home (upstream) and/or another distro?

No response

Expected behaviour

Every menuentry in /boot/grub/grub.cfg contains lines of the form:

  echo  'Loading initial ramdisk ...'
  initrd  /boot/initramfs-${VERSION}.img

Actual behaviour

For the newly installed kernel versions, the above lines are missing from the menuentry in /boot/grub/grub.cfg. This makes the new kernels unbootable. I have to restart the machine and pick an older kernel that was previously installed.

Running update-grub fixes the problem. The initrd lines then are added to all menuentrys in /boot/grub/grub.cfg.

Steps to reproduce

Pre-conditions (not sure which are actually relevant, but they might all be):

1. I have installed both the linux and the linux-lts package.
2. I have also installed package zfs (DKMS module).
3. Both kernel packages mentioned above are out of date.

Steps to reproduce:

1. Run sudo xbps-install -Su

Reproduce the issue with linux, linux-lts, and zfs installed by running sudo xbps-install -Su, then compare /boot/grub/grub.cfg before and after update-grub. Trace the kernel update path and its GRUB configuration handling; done means newly installed kernel menuentries include the expected initrd lines without requiring a manual update-grub.
