Another solution could be a small script that converts "long device
names" to small ones, using informations from /proc/partitions.
I join to the mail a portion of php script that does this task.
I think it could adapted easily to other more common script languages
(a Perl Guru should write that in a few lines...)
Usage: pc df
(or alias dfs='pc df')
