UFS: / over capacity

Similarly, I ran out of disk space … then quickly keyed Control-C to abort the upgrade, and so on.

I removed /boot/kernel.old, continued to move or remove other things e.g. /var/db/freebsd-update/*, it seems that:

  • no matter how much I remove, the file system remains over capacity.

With the drive connected to a different computer:

For any of the listed folders, does disk usage appear excessive (compared to a fresh installation of NomadBSD)?

Is the output from df(1) sane in this case?

Can UFS not recover from (not regain free space after) over capacity situations?
