Depends on whether you want to use legacy mountpoints or not. The mounted filesystems are divided up into two main SMF services, filesystem/minimal (enabled as part of single-user) and filesystem/local (not part of single user). There is also filesystem/root and filesystem/usr, but we'll ignore those for the purposes of this discussion. filesystem/minimal is responsible for mounting some basic filesystems, as documented in the method script (/lib/svc/method/fs-minimal): # Mount other file systems to be available in single user mode. # Currently, these are /var, /var/adm, /var/run and /tmp. A change # here will require a modification to the following programs (and # documentation): /sbin/mountall, /sbin/umountall, and # /lib/svc/bin/svc.startd. So if you want any of the above filesystems to be ZFS filesystems, you will have to do 'zfs set mountpoint=legacy' and put them in your /etc/vfstab. For all other filesystems, you can leave them as ZFS-managed mountpoints, as 'zfs mount -a' is run as part of filesystem/local. If you want /export/home to be a ZFS filesystem, you can still access it in single user mode by running 'zfs mount -a', but this is the same as if you used any other filesystem (albeit with /sbin/mountall). So short answer is: if your want /var, /var/adm, /var/run, or /tmp on ZFS, use legacy mountpoints and put in /etc/vfstab. All other filesystems can use standard ZFS mountpoints. - Eric -- Eric Schrock, Solaris Kernel Development http://blogs.sun.com/eschrock _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
