   I have a Gentoo installation that I'm trying to make bootable in 2   
   different machines.  On the first machine, the hard disk is seen as   
   /dev/sda; the root partition becomes /dev/sda1 and swap /dev/sda2.  On   
   the second machine the disk is seen as /dev/sdc and root is /dev/sdc1   
   while swap is /dev/sdc2.   
      
   I have set up 2 kernel configurations suitable for the hardware of each   
   machine plus the correct root= kernel parameter (root=/dev/sda1 on the   
   1st machine and root=/dev/sdc1 on the 2nd.)   
      
   In /etc/fstab I use labels instead of device names to do the mounting:   
      
   LABEL=GentooRoot /    ext3 noatime 0 1   
   LABEL=GentooSwap none swap sw      0 0   
      
   At first it works (when booting in the 1st machine where I've set it   
   up).  However, booting it in the 2nd machine results in swapon   
   complaining that /dev/sda2 does not exist (which is correct).  It fails   
   to pick /dev/sdc2 (LABEL=GentooSwap).   
      
   Now, moving the hard drive to the 1st machine again and trying to boot   
   from it results in a non-bootable system; the command 'fsck -C -T -a /'   
   (this happens in /etc/runlevels/boot/checkroot) complains that /dev/sdc1   
   cannot be repaired, and the boot process stops.  That's totally wrong;   
   it should check sda1, not sdc1.   
      
   Probably I'm doing something wrong here. :P
