I just used apt-get install cryptsetup to install the missing cryptsetup app
and also installed (previously to cryptsetup) IcedTea; i haven't used apt for
anything else in a long time. Just one or two days ago i had cryptsetup
installed!
About the filled root partition: i have a separate partition for /var, /boot,
/home, /opt, /usr and /usr/local, so i think that logs (separated in its own
/var partition) ain't the problem, and... i really can't find big files in /
or /root that could ever fill anything at all... neither some big corrupt
config file in /etc ... weird! I do have some 320 MB in /dev/shm (five 64 MB
pulse-shm-xxxxxxxxxx) and over 500 MB somewhere in /sys/devices/pci/ ... what
could this mean?
Could a malevolent Java applet embedded in a webpage be able to delete my
local cryptsetup app???
