Comment 2 for bug 219568

1. Yes, that is quite odd. Please stick `set -x` in the top of /lib/partman/check.d/12system_partitions_formatted and attach /var/log/syslog to this bug report after that message pops up.
2. It tells you which mount point is too small. I think that's suitable, but why do you think that the device name would be better?
3. Indeed, I had hoped to fix that in this release cycle, but I missed the string freeze cutoff so it will have to wait for 8.04.1 or 8.10.
