[Ltib] "no space left on device" during installing a rpm on the target

[CB]

Hello!

Today I ran into an odd problem.
To avoid flashing my whole rootfs all over again on every try of my tool, I
wanted to install the generated RPM on the target. I fixed the paths with --root
and --prefix. Also the tmp-dir was set to point to the rootfs (ext2 partition on
a SD card). But 'rpm' fails during unpacking with "no space left on device"
despite 'df' shows 40MB of free space (rootfs is 100MB total).
The rootfs image on the host machine is generated correctly containing my tool.
So the RPM file seems to be correct.
Any suggestions on how to track down the problem?

Christoph
