 On Linux:
mkfs.ext2 -L commons /dev/sda4            # optionally -O ^dir_index,^ext_attr

On NetBSD:
dkctl ld0 listwedges                      # find the wedge, e.g. dk3 /
GUID b5bff367-...
mount -t ext2fs NAME=b5bff367-4977-4887-bea0-7e42f7a04fe4 /mnt

In fstab:
NAME=b5bff367-4977-4887-bea0-7e42f7a04fe4  /commons  ext2fs  rw  0 0

To repair: use Linux e2fsck or pkgsrc e2fsck -- never
/sbin/fsck_ext2fs on 11/-current

Setting a GPT partition label (`gpt label -i 4 -l commons ld0` on
NetBSD, or `sgdisk -c 4:commons` on Linux) gives you `NAME=commons` in
fstab.
