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

330M    /lib
311M    /lib/modules

got several kernels here.

linux-headers-2.6-amd64                install
linux-headers-2.6.32-5-common            install
linux-headers-2.6.38-2-amd64            install
linux-headers-2.6.38-2-common            install
linux-headers-2.6.39-2-amd64            install
linux-headers-2.6.39-2-common            install
linux-headers-3.0.0-1-amd64            install
linux-headers-3.0.0-1-common            install
linux-headers-amd64                install

after purging, only took

# du -sh /lib
128M    /lib

Thanks for your help. It's done.

I hope yes :-)

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

No, because its a "virtual" one:
