Is there a method for adding an option line in the GRUB loader (Ubuntu 10.10) that directs the boot specifically to a named USB device? If so, can you provide an example of the line to add? This is for use in an office environment where people would prefer to select their boot options from a menu.
I think there is, but at the moment I can only find reference material on booting by uuid like so: http://grumpymole.blogspot.com/2007/05/ubuntu-how-to-edit-grub-boot-parameters.html I will update my answer if I run across a label= example
edit:if you want to boot a kernel image off of a specified device i am still at a loss atm, but here's a link for root fs by label: http://www.linuxforums.org/forum/red-hat-fedora-linux/23010-root-label-grub-conf.html
they reference redhat based distros liking this approach and i used to be a redhat guy, so i can't tell you if this is redhat dependent or not. i go with uuids in my current situations
this guy wrote a patch a LONG time ago: http://osdir.com/ml/boot-loaders.grub.bugs/2004-02/msg00105.html
looks like the invocation is: kernel /PATHTOKERNEL ro root=LABEL=MOUNTPOINT
