Public bug reported:
The kernel in Jammy is a bit larger than the one in Focal and our
previous /boot partition size calculation (LP: #1716999) likely didn't
take into account adding modules like nvidia to the initramfs.
Subsequently, we need to revisit the size calculations for Focal.
I'm utilizing cryptsetup and nvidia modules and have a 164M initrd when
using lz4 (the default in Focal) compression. Using the same formula we
previously did we end up with this:
2* (3*11 + 4*164 + 11) = 1400
So modifying the maximum size to 1536 seems reasonable, the current
minimum is 512 which is actually a bit too small for an initrd with less
modules e.g.:
2* (3*11 + 4*62 + 11) = 584
So the minimum should also be increased to 768.
The default compression level for Jammy is currently being discussed and
until that is decided we shouldn't make changes to partman-auto for
Jammy.
