Does LFS still have problems when a partition becomes nearly full? I haven't
talked to Konrad in a long time, nor have I played with LFS in a long time,
and then it was on a small disk (well, small by today's standards; I believe
it was a 20GB.)

Performance from LFS was outstanding, but I never pushed the disk beyond,
say, 60% capacity, and ISTR hearing of troubles with lfs_cleanerd on disks
that were approaching full capacity.

I would be more than happy to give [that developer] root access to a test
machine to play with ZFS, to assess its viability. Can you relay that
message for me? :)

In the meantime, I shall play with LFS on this 15GB deathstar I've got that
I've been meaning to wipe in any case.
