Hi Jonas.

Mainly for consistency across the 10 distros that are installed on this 
machine. I don't use Label or UUID's to mount them, but just point to the 
device nodes for the partitions I want to mount.

Anyway, I've resolved the problem now by running update-initramfs after 
listing the load order of the modules in /etc/initramfs-tools/modules as 
Default loading:

New load order:

sudo update-initramfs -u -k `uname -r`

Now fdisk -l shows the newly added pata drive as sdc instead of sda, and the 2 
sata drives are back at sda, and sdb where they should be thus matching their 
position on all the other distros.

Job done, and I've learned a bit about the initramfs at the same time.

All the best.
