Another way to solve this -- sort of oldfashioned but very elegant -- is
to use labels. Say you want to label drives tv0 to tv2:
* ext2 and ext3: e2label or "tune2fs -L tv0 /dev/sde1"
* XFS: "xfs_admin -L tv1 /dev/sda1" (max 12 characters, unmounted drive)
* JFS: "jfs_tune -L tv2 /dev/sdb1" (max 16 characters)
In /etc/fstab,
LABEL=tv0 /tv0 ext2 auto,defaults,user,exec
0 0
LABEL=tv1 /tv1 jfs auto,defaults,user,exec
0 0
LABEL=tv2 /tv2 xfs auto,defaults,user,exec
0 0
No matter how you attach the drives -- SATA channel, USB -- they will be
mounted where they should.
This has been around for so long that it's rumored the guy who came up
with it also invented the wheel!
I tried that, but my initrd said something about not finding
/dev/disk/label/ROOT when I passed root=LABEL=ROOT, and I had labeled
the root filesystem with e2label. So either something doesn't work with
labels in 2.6.15, or initramfs-tools doesn't generate an initrd that
supports it.
If someone knows how to solve that part of it, then I will be using
labels to fix this.
