Note: I set the LANG environment to posix because...

1/ My system is in Spanish so when posting some output to this mailing 
list it is desiderable to get the results in English

2/ I only have a small set of locales available (I mean, no "en_US.utf8" 
in this system):

sm01@stt008:~$ locale -a
C
es_ES.utf8
POSIX

Hmm... you "/lib" seems a bit bloated (mine is 94 MiB), I would look 
inside it:

du -h /lib | grep "[0-9]M" | sort -n -r | less

I hope yes :-)

You can run "df -ah" to see all of the "available" partitions.

No, because its a "virtual" one:
