- Create ZFS filesystem hierarchy
The lz4 compression algorithm is fast enough to be used by default, even for uncompressible data.
zfs set compress=on zroot
Create a Boot Environment hierarchy
zfs create -o mountpoint=none zroot/ROOT zfs create -o mountpoint=/ -o canmount=noauto zroot/ROOT/default mount -t zfs zroot/ROOT/default /mnt
Create the rest of the filesystems.
zfs create -o mountpoint=/tmp -o exec=on -o setuid=off zroot/tmp zfs create -o canmount=off -o mountpoint=/usr zroot/usr zfs create zroot/usr/home zfs create -o exec=off -o setuid=off zroot/usr/src zfs create zroot/usr/obj zfs create -o mountpoint=/usr/ports -o setuid=off zroot/usr/ports zfs create -o exec=off -o setuid=off zroot/usr/ports/distfiles zfs create -o exec=off -o setuid=off zroot/usr/ports/packages zfs create -o canmount=off -o mountpoint=/var zroot/var zfs create -o exec=off -o setuid=off zroot/var/audit zfs create -o exec=off -o setuid=off zroot/var/crash zfs create -o exec=off -o setuid=off zroot/var/log zfs create -o atime=on -o exec=off -o setuid=off zroot/var/mail zfs create -o exec=on -o setuid=off zroot/var/tmp
Cleanup
ln -s /usr/home /mnt/home chmod 1777 /mnt/var/tmp chmod 1777 /mnt/tmp
