Enabling persistent naming in /etc/fstab is easy, just replace the device name in the first column by the new persistent name. In my example I would replace /dev/sda7 by one of the following:

/dev/disk/by-label/home or /dev/disk/by-uuid/31f8eb0d-612b-4805-835e-0e6d8b8c5591 Do so for all the partitions in your fstab file.

... is this really truely ?

I have to use :

UUID=31f8eb0d-612b-4805-835e-0e6d8b8c5591 /home

or I understood somewhat wrongly.

It works, yes. But I prefer LABEL over UUID:

LABEL=HOME-jfs /home nodev,nosuid,noatime 0 2

Found this howto easy & very usefull :) Have got a few HDDs & USBKeys that love to be (disk-label) mounted so easy but still a sure way (by easy i mean, compared to udev rules ;).

but I havn't this /dev/disk/by-label directary,why? mawchmail@gmail.com

That's because that directory is actually created (and destroyed) dynamically when you attach (or detach) some disk or partition that has a label! A bit scary for the uninitiated, but true....
