Grml wiki indicates that grml can use disk labels/UUIDs as root= option for booting [1]. What's the correct syntax for that?

Ah, that's where I learned about stable root device naming convention. I've read it before, but only vaguely remember the knowledge came from grml when I need it, but searched the wrong place -- grml wiki. thanks again mika.
I did not document it in the grml wiki yet because I'd like to write some more documentation about it before. Upcoming grml releases will very probably use mounting by UUID for main partition (the libata merge of >=2.6.19 forces the decision), I've to make sure the upgrade path works fine for all users then.
A side question, is the UUID get assigned during mkfs or partition creation, or...?
The UUID is usually assigned with running mkfs. Some filesystems provide an interface to change the UUID later on, like with "xfs_admin -U $UUID".
