I been putting this off but it looks like the newer kernels are going to
push me to changing this real soon. I have a older system, Abit NF7 2.0
motherboard with the older IDE drives. I'm still using the older IDE
drivers. This is what I have currently:
hda Actual hard drive OS on this
hdb Actual hard drive Not in use
hdc Actual hard drive home partition
hdd DVD burner Duh! It's a burner.
sda Actual hard drive connected through a SATA PCI card. Misc stuff.
The advice by the other posters to label your disks is a good one. I'm
using labels too. Not sure why I didn't think to mention it :P
Applying labels to your filesystems is trivial. Simply use the e2label
utility (it's in the sys-fs/e2fsprogs package and installed by default,
so there's nothing new to emerge). For example, if your hda1 is your
root partition and your hda2 your swap, you can label them like this:
e2label /dev/hda1 GentooRoot
e2label /dev/hda2 GentooSwap
Note: hda1, not just hda. You are labeling the filesystem on a
partition, not the whole drive.
After you label all your filesystems, you simply modify your /etc/fstab
like this:
Before:
/dev/hda1 / ext4 noatime 0 1
/dev/hda2 none swap sw 0 0
After:
/dev/disk/by-label/GentooRoot / ext4 noatime 0 1
/dev/disk/by-label/GentooSwap none swap sw 0 0
That is, you simply change "/dev/blah" to "/dev/disk/by-label/DriveLabel"
and that's it.
Or you can do it by uuid, all the info you need can be picked from this
output:
$ ls /dev/disk/by-uuid/ -l
Then just add lines to fstab like this:
UUID="6ea2b219-0bcc-4c90-9960-82a9659e6d0e" / ext4 noatime 0 1
True, except that for mere mortals, Labels are slightly easier to read and
understand :)
And that, I find, is less prone to mistakes.

Hmmm, I use resierfs for my file systems, most of them anyway. I still
use e2fsprogs to change those?
Is there a way to boot a Gentoo/Knoppix CD and make it use the PATA
drivers? That way I can boot it and see exactly how it will name them
and what drive is what without actually changing anything at all. Is
there a boot option "noide" or some other switch I can use?
