OK (thanks also for the others suggesting this, I haven't checked docs
if this is mentioned somewhere.).

Hmm, that did not help.
How much disc-space someone need on the partition where LTP resides
(where the tests are performed)?
$ LANG=C LC_ALL=C df -T
Filesystem Type 1K-blocks Used Available Use% Mounted on
rootfs rootfs 17753424 12825524 4003024 77% /
udev devtmpfs 1960968 4 1960964 1% /dev
tmpfs tmpfs 788020 888 787132 1% /run
/dev/sda2 fuseblk 465546236 107358584 358187652 24% /host
/dev/loop0 ext4 17753424 12825524 4003024 77% /
none tmpfs 5120 0 5120 0% /run/lock
none tmpfs 1970048 156 1969892 1% /run/shm
Can I use a different partition where I have more disc-space available?
