I did this long ago, therefore I can switch between the old and new kernel easily. > For example, don't put "/dev/sda3" in your fstab, but label that > filesystem with a name like "root_fs" and use > "/dev/disk/by-label/root_fs" in fstab. > > Ext2/3/4 filesystem can be labeled with the "e2label" tool.

And how does this help the kernel to find the root device where /etc/fstab is located ? - Jörg BTW: Yes, I will boot next time with a LABEL entry in the kernels boot option, but I still don't want a kernel that assigns devices in random order.
