always adequate. 240/63, another very common configuration...
IME, 31 KiB is still enough to contain a core image when not needing
costly features such as btrfs, LVM or RAID support.
That's what "not always adequate" means. Partitioning with less than 63 SPT
isn't all that unusual on old PATA disks either.
Really ? Even amongst my oldest PATA disks (less that 1 GB capacity), I
could find only one having less than 63 sectors per track.
And, sometimes those old
configurations have other things using the boot track. Maybe Grub2's installer
rejects using that space if it's not empty of recognizable content?
Maybe. Without the complete error message from grub-install we cannot know.
Anyway, the Debian installer calls grub-install with the --force option
so that if embedding in the post-MBR area is not possible, the core
image will be stored as a regular file in /boot and accessed using block
lists unless the filesystem does not support it. AFAIK, only btrfs is
not supported with this setup, and a separate /boot is very unlikely to
use btrfs.
XFS has not the same limitation as BTRFS?
Well, I don't know. I have never used it. But using XFS for the /boot
partition seems very unlikely too.
