Hi,
starting with the 2.6.36-r5 kernel of the Gentoo sources my boot device
changes. With 2.6.35 and below it is alway /dev/sda3, with the new kernel it
seems that anything that is internally connected with USB is assigned a
device first. Since my computer has an internal media bay (and my monitor
has such a thing also) the first HD moves - it I take care it is now
/dev/sde3. However, if I forget to switch on the monitor and do this later
or if an USB stick is already plugged in at boot time, the HD gets a
different device number again.
Can somebody else confirm such a behaviour with the 2.6.36 kernel and how
can this brought back to normal operation?
This has been solved long ago: Label your filesystems and mount them by
label. 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. For example:
e2label /dev/sda3 root_fs
After that, modify your fstab accordingly.
