Anyway, make sure you have a bootable Linux CD/DVD handy. That
way, you
won't be able to blow anything up and can boot from it in order to
change your /etc/fstab and grub conf.
Alternatively, give your partitions Labels and reconfigure /etc/
fstab to
use those.
Then you don't have to worry about the changes to the device-names.
I second Joost's recommendation. I don't think you can use labels
on the
kernel command line, so your grub will have to know for sure which
device to boot.
Actually, you can:
http://www.ibm.com/developerworks/linux/library/l-boot-rootfs/index.html
(Read the section below "Use a label"):
fstab:
LABEL=ROOT / ext3 defaults 1 1
LABEL=BOOT /boot ext3 defaults 1 2
LABEL=SWAP swap swap defaults 0 0
LABEL=HOME /home ext3 nosuid,auto 1 2
This syntax never worked here. Always resulted in an unbootable
system. Only the /dev/disk/by-label/ syntax works reliably.
Because you need to use the `root=/dev/sdaX` format in GRUB?
I think an appropriate initrd/initramfs is required - I'm not sure if
there are any other requirements - to use labels in GRUB. I think it's
common to do things this way on RedHat systems, maybe with some other
distros - that's what fouled me up when I tried using labels in GRUB;
I just found grub.conf examples using them, and was unaware of this
requirement.
Stroller.
