Ubuntu Studio UUID versus /dev/sdaxx


I am using is Ubuntu Studio 7.04 on a multi-boot machine. My question is: is it possible to replace the UUID values in Ubuntu's /etc/fstab with /dev/sdaxx values without running into deep trouble? Every time I change one of the other distros, Ubuntu Studio will not run except by using Ctrl-D. This can be fixed by getting the correct UUID value with vol_id -u /dev/sdaxx and entering the correct UUID into Ubuntu's /etc/fstab, but it is a pain.

Is the above replacement possible?

Thank you

Using /dev/sdaxx is OK so long no hardware is changed - and that my include a memory stick! A safer and more transparent solution is to mount by label. Just label your partitions and replace the UUID=<hash name> by LABEL=<partition label name>.


There is another reason for this: on one of my PC's, kubuntu (feisty) thinks that my IDE disks are scsi and assigns the /dev/sdaxx and /dev/sdbxx to it. This gives rise to rather confusing differences between fstab's in different distro's on the same hdd. No problem to assign by the same label, though.

HTH,

Thanks OldAl,

I'll give it a try. I forgot to mention that I have 2 hard drives: an SATA that came with the machine and a 2nd one which is an EIDE. More on the second hard drive latter.

I will probably just change one setting first to see how it goes and to make sure that I change everything I need to.

Take care,
NicholasA
