That's pretty seldom. $ find /usr/share/man/cat* -type f | wc -l 3277 $uname -v FreeBSD 5.0-CURRENT #0: Sat Sep 30 17:31:17 CST 2000 grog@wantadilla.lemis.com:/src/FreeBSD/WANTADILLA/src/sys/compile/WANTADILLA That's about 7.5 man pages per day. This is on my main machine, and I suspect I use man pages more than most. More to the point, how many broken /usr file systems have you *ever* had with FreeBSD?
