Re: 2 Disks (by label/UUID)

I had also the issue with the UUIDS. However, I did not flash the kernel
in-between, I only changed /etc/fstab. 
Also -- at least in my case -- it was sufficient to try to mount *some*
filesystem, not necessarly the rootfs. (Maybe, Stuart, can you try this
too? Does it break if you use UUIDS on some other fs than the rootfs?)
I do not have the hardware here to hook up the serial interface on my
thecus, so I cannot debug that right now.

BTW, As I made a backup of /etc before reinstalling to armel, I actually
have this offending fstab, (just the UUID changed, as this stick is
still in use...) 

# /etc/fstab: static file system information.
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/md0        /               ext3
defaults,errors=remount-ro,noatime,commit=36000 0       1
/dev/md1        none            swap    sw              0       0
