Hello, I am using AUFS to my diskless Servers, I export a root (xfs via nfs) as RO, and directory as RW (xfs via nfs).
I am using AUFS 20080310 Mounting system root is: mount -n -t aufs -o \ xino=/xino/.aufs.xino,noplink,udba=inotify,nowarn_perm,br:$R \ W=rw:$ADICIONAL=ro+wh:$GERAL=ro+wh:$MAINROOT=ro aufs $NEWROOT In a system WITHOUT aufs i get: 8<----------------------- [EMAIL PROTECTED]:~$ cd /var/lib/php5/ [EMAIL PROTECTED]:/var/lib/php5$ ls -ld drwx-wx-wt 2 root root 6 2008-03-11 19:09 .
