The kernel in Jammy is a bit larger than the one in Focal and we 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. |

[Impact]
All new installs of 20.04.
[Test case]
1) Install Ubuntu 20.04 on a system
2) Validate that the size of the /boot partition is greater than or equal to 768MB; should be somewhere between 768MB and 1536GB.
[Regression potential]
This may adversely affect installs on tiny disks, by taking up more space for the /boot partition than was previously taken, at the cost of / or /home. As such, failures to install due to insufficient space on a partition, or failure to partition a disk that was previously working should be investigated as possible regressions.
This is a corner case in general since there is no requirement to allocate a separate partition for /boot in the default configuration, and if you are using a non-default configuration where /boot must be a separate partition, you probably also don't have a disk so small that an additional 256MB of disk usage is a problem.

[FFE Discussion]
Now that changes to the initramfs compression level have been settled for jammy (https://launchpadlibrarian.net/590731434/initramfs-tools_0.140ubuntu12_0.140ubuntu13.diff.gz) we need to update the size of /boot so that the additional size of the initrd is taken into account. This should be done before the Beta as more people may be installing Ubuntu then and we don't want them to have undersized /boot partitions given the problems that this can cause.
Using the same install of Ubuntu with cryptsetup and nvidia modules my initrd is now 188 MB. Plugging that into our formula gets:
2* (3*11 + 4*188 +11) = 1592
While that's divisible by two, I think we should bump it a bit more to 1848.
