Dear internet & users & robots & AIs & other entities with access to digital,
one fine day... decided to compile the latest currently available kernel under Debian 11.
last time did that it was Debian 9 and with a bit of tinkering it worked.
now of course - things are different - again.
after a bit of even more tinkering, managed to compile the kernel and all modules (i5 took 100Min) https://dwaves.de/2022/05/13/gnu-linux-debian-11-should-also-work-for-ubuntu-compiling-the-latest-kernel-straight-from-kernel-org-linux-x86-5-17-7-work-in-progress-complexity-is-the-enemy-of-good-software-developmen/
when it comes to:
sudo make install
sudo make modules_install
but after reboot...
it won't find it's previous lvm2 volume group + luks2 encrypted /root
Begin: Running /scripts/init-premount ... done.
Begin: Mounting root file system ...
Begin: Running /scripts/local-top ... Volume group "name-vg" not found
and then falls to "emergency" initramfs prompt...
imho boot partitions should be at least 1GB by now... because have a few kernels installed and the whole thing blows up, because it is out of disk space.
in initramfs prompt:
... nothing... does not find the luks2 encrypted /root partition.
but when booting from usb stick https://dwaves.de/2021/04/11/ideallinux2021-updated-optimized-bootale-gnu-debian-10-9-64bit-non-free-based-usb-stick/
it shows up... ?
(will retry with a 4GB /boot partition and report back X-D)
btw: it was not a problem, getting "back in there" via chroot
and accessing all the data like this: https://dwaves.de/2021/04/11/gnu-linux-debian-10-dead-boot-partition-stuck-at-grub-prompt/
via this: https://dwaves.de/2021/04/11/ideallinux2021-updated-optimized-bootale-gnu-debian-10-9-64bit-non-free-based-usb-stick/
actually when chrooted into the luks2 encrypted /root partition,
tried a re-install latest kernel. and was able to watch initrd.img-5.17-amd64 get bigger, and bigger and bigger...
and finally fill up all of the (per default under many distroy) 512MBytes of /boot
