+ We often see people coming at the lug who have issue of having "not 
+ enough
+ space on their home", and who want to resize their partition. Of

+ This seems to me quite complex, when compared to a graphical interface 
+ to resize
+ a disk ( as would diskdrake or palimsest be ).
+
+ And of course, that's also something that was tried at Mandriva, with

+ kind of hack to perpetuate "because it worked on my computer so it 
+ would work on my server" is
+ a so good idea.  ( on the other hand, if people do unclean stuff, I 
+ will have less effort to keep my job
+ or to take their )
