Linux boot with UUID

Hi Dudes ;)

Can I boot a LinuxInstallation with a UUID instead of an /dev/sdb1 ?

I want a bootable USB-Stick with OpenSuse , mintppc11 , debian8.2 and fedora17.

I ask , because my mintppc11-usbstick boot if i turn my X1000 on (after i paused for 10mins).
But a second boot after the first one boots into a Kernelpanic (cant find a rootfs at xxxx).
I boot with the same CFE-Var that i tried before.

This will be a quick reply as I am on the QM2 with only access to satelite internet (charged by the minute) I hope to have better access once I reach Scaramento next week.

In answer to your question, yes, but not easily. UUID, and LABEL booting require udev to have started to create these. I've been looking at this for another A-Eon project.. It appears to need a small initrd which can then activate udev and names then pass the control over to the main system.

What bootargs are you using? - you should have a rootdelay=10 or similar in.

I intend to look at this more over the next few weeks. stay tuned.

Hi daz

I try with rootdelay=10 and 20.
But i found a Failure later at /etc/fstab . OpenSuse (on /dev/sda4 from my Sata-HDD) have a UUID there.
If i change them manualy to /dev/sda4 I can boot onto Lxde-Desktop but with no Ethernet interface up.

The Opesuse-13.2.tar.gz from Xeno74 has the same Problem with UUID but has a working Netwotk .

I will try my Trick ? on Fedora17 .
