The block counts as given by df (see below) cannot possible be right. The
df man page offers the following explanation:

Note that the printed count of available blocks takes minfree into
account, and thus will be negative when the number of free blocks on the
filesystem is less than minfree.

That's fine, but how can the used block count be so high when the /tmp
directory is supposed to be cleared at boot time? The result is that ed/vi
cannot create a file because it thinks that /tmp is full (see below). (As
root, ed/vi doesn't complain about /tmp being full, of course.) Am I
pushing my luck with large partitions or is this something else?

Another weird thing has to do with nsectors and ntracks. Mkfs uses 218
sectors/track and 5 tracks/cylinder to format the partitions. disklabel
now shows 217 sectors/track; at other times, disklabel reports 32
sectors/track and 64 tracks/cylinder. Is this relevant at all here?

Any suggestions?
Thanks in advance	--Balazs
