Is it also capable of shrinking filesystems? I've sometimes wanted to grow
my /var or / slice using space freed by shrinking /usr (on a default
partitioned disk). Up to now I've solved it through symlinks, but that
doesn't really deserve the beauty award. I'd imagine a lot of new users
wouldn't mind being able to change partition size on a fully configured
machine without having to resort to backup, reslice, restore....
Anyways, sounds like a very handy tool already!
Just my $0,02
