Actually not. As mentioned in
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1076952>, the recipe
had MIN=PRIORITY which resulted in the size being stuck to MIN (538 MB)
regardless of the available disk size.
Only on smaller disks it has ~512MB, so that could be changed to ~768MB
to be consistent with /boot.
OK. But with MIN=806 and PRIO=850 (how did you define this value ?), the
increment factor (PRIO-MIN=44) is too low to allow any growth when
partitioning without LVM.
Explanation: raw increment factors are normalized on a base 100 and
rounded to integers. It means that it a raw increment factor is less
than 1% of the sum of all increment factors, then the normalized
increment factor equals 0 and the partition cannot grow.
The sum of raw factors is over 80000, so 44*100/8000=0,55 rounded to 0.
When partitioning with LVM, the lvmok partitions (/ /home swap...) are
ignored for the non-lvmok partitions (efi, /boot) calculation size.
Instead, a lvm partition with PRIO=900 is used. With such low value, the
normalized increment factor for the ESP equals 4 and the maximum size
1075 MB is reached with a disk size of 9 GB.
I anticipated this and looked at partman-auto-lvm for way to set the
same partition sizes with and without LVM. Not easy.
