Yes, labels . . . been thinking of doing this for the last two years!  I gu=
ess=20
I will have to use reiserfstune for my reiserfs partitions.  What about xfs=
 -=20
will xfsprogs do it?

Thanks for the tip.  The thing with the conventional device numbering syste=
m=20
is that you know which one is first, which second, etc.  With Labels I'll=20
have to add something to it to remind myself that this is the first=20
partition, etc.  Can I have blank spaces in the Label name?
=2D-=20

Mick
