Hm, I keep /home out of /usr, so there's only a symlink (for the
obvious compatibility reasons) /home@ -> export/home.
BUT, and now the big surprise, maybe a possibility:
% mount -p
/dev/ad0s1a / ufs rw 1 1
devfs /dev devfs rw 0 0
/dev/ad0s1d /tmp ufs rw 2 2
/dev/ad0s1e /var ufs rw 2 2
/dev/ad0s1f /usr ufs rw 2 2
/dev/ad0s1g /export/home ufs rw 2 2
devfs /var/named/dev devfs rw 0 0
linprocfs /usr/compat/linux/proc linprocfs rw
0 0
^^^^ Haha!!!
It seems that the linprocfs prevents umounting of /usr because its
mountpoint /usr/compat/linux/proc is de facto INSIDE /usr.
I've checked this while in SUM: When umounting linprocfs prior to
/usr, no problems occur.
I'll speak to Mr. Tritter so he can stop his investigations. Seems
that we found the reason.
Thanks for your help.
Seems that I'm too stupid to own a computer. :-)
