 Posted: Sun Apr 20, 2025 12:27 am Post subject: can GRUB or LILO? |
 |
|
I'm wondering if either can boot using device id or label. I've installed Arch to a usb key, but its not very reliable or portable. Its a two fold problem.
GRUB will not correctly mount the root device when trying to boot. It says file system unknown even though I've tried both ext2 and ext3. I even let the arch installer auto prepare the drive which creates a seperate partition for /boot. I've had it work correctly with pclos minime installed to this same drive. Any ideas on why it won't?
LILO will boot arch correctly, but its not very portable because of device names changing, ie /dev/sdb1. I know grub will boot by dev-id, but can LILO? Google isn't giving me much success.

| Not a definitive answer, but everything I've read says that LILO is NOT able to boot by uuid.

At This site there is a discussion of using GRUB and LILO together to achieve chainloading. I know that it is not necessary to use LILO to achieve chainloading. I have recursively chainloaded, moving from one GRUB to another to another. Large disks and different disks can sometimes cause challenges, but carefully handled these can be overcome.
Like tlmiller, I have seen discussions that suggest that LILO is not yet able to handle UUID conventions and suggests changing to the appropriate /dev name instead - and these have also recently changed from the use of /dev/hda, hdb, etc. to sda, sdb, etc. names. It may be worth experimenting with various settings to see what works and what does not at this stage. |

| Yes, lilo will boot by uuid. Instead of root= you have to add it to the append line as in append="root=/dev/disk/by-uuid/xxxx"

| Seems to work like a charm. Now if I'd just made the partition bigger lol.
