I use legacy mountpoints for / and /var, but it's a little kludgey, and from what I recall a legacy mountpoint requires setting the mountpoint property explicitly on anything mounted under it. I assumed you had made the change to obviate the need for most of this extra bookkeeping with fstab and explicit mountpoint properties that don't match the zpool dataset path. E.g., right now I have: rpool/ROOT mountpoint=legacy mounted at / rpool/ROOT/var mountpoint=legacy mounted at /var rpool/chroot mountpoint=/var/chroot rpool/crash mountpoint=/var/crash rpool/home mountpoint=/home (default) rpool/export mountpoint=/export (default) ... and critical_filesystems_local=/var in rc.conf entries in /etc/fstab for / and /var. (This is all inside a chroot with the `real' / mounted from a ramdisk, of course.) So I'm guessing with your change and critical_filesystems_zfs=/var, I could: - skip the fstab entry for /var, - have only rpool/ROOT with mountpoint=legacy, and - have /var and all the file systems under /var use default mountpoints. (I haven't looked at or tried the changes yet!)
