I've been moving a lot of machines from 9.0 to 9.1 with some patches
this days (like tmpfs-nrbtree). I inject some code inde /etc/rc.d/zfs to
update this. I'm adding this to /etc/fstab:
tmpfs /tmp tmpfs rw,nosuid 0 0
After this I'm changing /etc/rc.d/zfs:
@@ -23,6 +23,12 @@
zfs_start_main()
{
+ umount /tmp
+ zfs destroy mypool/tmp
+ rm -rf /tmp
+ mkdir -p /tmp
+ chmod ugo+rwxt /tmp
+ mount /tmp
zfs mount -a
zfs share -a
if [ ! -r /etc/zfs/exports ]; then
After reboot zfs filesystem for tmp is gone and tmpfs is in charge.
The code is harmless upon reexecution and just does the job. I haven't
found easier way of doing this.
