Yes, I noticed that already :-) > > Only on smaller disks it has ~512MB, so that could be changed to ~768MB > > to be consistent with /boot. > > OK.

The ESP seems to be a special case regarding the calculation of the disk size. There was a changing https://salsa.debian.org/installer-team/partman-auto/-/commit/a5df6f5c98a58bb81e688fc3c2b6532833a8e4d0 which bumped the 512 to 538 MB and the 1024 to 1075 MB.

Not easy. Hmm, that seems a bit out of my skills :-( But if a value of 538 worked for 512MB, why should 806 not work then for ~768MB ?
