I found out what i was missing:
kernel: WARNING: /export/linux/root was not properly dismounted
After doing an fsck which found and corrected some errors, i tried again.
Now tunefs reports:
root@antsrv1 [~] # tunefs -p /export/linux/root
tunefs: ACLs: (-a) disabled
tunefs: MAC multilabel: (-l) disabled
tunefs: soft updates: (-n) enabled
tunefs: maximum blocks per file in a cylinder group: (-e) 2048
tunefs: average file size: (-f) 16384
tunefs: average number of files in a directory: (-s) 64
tunefs: minimum percentage of free space: (-m) 8%
tunefs: optimization preference: (-o) time
tunefs: volume label: (-L)
Yet mount says:
root@antsrv1 [~] # mount|grep linux/root
/dev/da0s1a on /export/linux/root (ufs, NFS exported, local,
soft-updates, acls)
And ACLs *do* work:
root@antsrv1 [/export/linux/root/debian/usr/local/share] # ls -ld wallpaper/
drwxrwxr-x+ 2 root wheel 512 May 30 16:05 wallpaper/
root@antsrv1 [/export/linux/root/debian/usr/local/share] # getfacl wallpaper
#file:wallpaper
#owner:0
#group:0
user::rwx
user:rebehn:rwx
group::r-x
mask::rwx
other::r-x
User rebehn is able to write to the directory "wallpaper".
Strange, that tunefs still reports that acls are disabled.
