I partitioned this system before /modules arrived, and I barely have enough space in / now (about 3 meg free). That shouldn't affect this issue though; I do have separate /usr, /var, and /tmp.

(I know it's a long shot...) Interesting idea, though I'd be surprised since I think the system time is set via ntpd, is it not? `date' seems to recover nicely every time anyway. A power surge could indeed play with CMOS though... but how would I test for this while the system is running? -- Doug Lee d...@dlee.org http://www.dlee.org SSB BART Group doug....@ssbbartgroup.com http://www.ssbbartgroup.com "Pray devoutly, but hammer stoutly." --Sir William G.
