You should check the return value of chdir(). Otherwise
we get the following warning message at the build time.
Can we actually fail to change directory to '/' ? Otherwise I think the
warning should be silenced so the build is clean.
It is theoretically possible, but in practice it means you either have
failing hardware or your kernel is broken somehow, both of which should
be causing all kinds of other issues, and thus we don't really gain
anything from trying to catch the error.
