Harddisk Linux Ku

Partisi ku untuk linux aku jadikan satu. Ruang yang aku sediakan hanya sekitar 7G. Berikut detailnya:

arahmaiani:/# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda8 7.4G 6.7G 331M 96% /
tmpfs 570M 0 570M 0% /lib/init/rw
udev 10M 76K 10M 1% /dev
tmpfs 570M 0 570M 0% /dev/shm
/dev/hdc 4.0G 4.0G 0 100% /media/cdrom0

Utilisasi di /dev/hda8 sudah mencapai 96%! Waduh, gawat ini. Lalu saya coba lihat di direktori mana sih ruang yang terbesar terpakai?

arahmaiani:/# du -xskc * | sort -rn | head -n 10
du: cannot access `proc/12741/task/12741/fd/3': No such file or directory
du: cannot access `proc/12741/fd/3': No such file or directory
7632073 total
3550288 usr
1789180 var
955008 home
920799 proc
197400 lib
136616 opt
41572 boot
30588 etc
4428 sbin

Kala sukses menginstall truecrypt, saya cicip Lenny. Lantas saya coba dist-upgrade ke Lenny, justru muncul pesan ini:
# apt-get dist-upgrade
..
...
...
590 upgraded, 268 newly installed, 18 to remove and 1 not upgraded.
Need to get 1020MB of archives.
After unpacking 763MB of additional disk space will be used.
E: You don't have enough free space in /var/cache/apt/archives/.

Sudah saatnya menambah kapasitas harddisk-kah?
