[Trisquel-devel] [PATCH] guard fuser -k in createjail against there being no open file handles

[Andrew 'Leny' Lindley]

The existing 'fuser -k $CHROOT-tmp' causes makepackage to fail when
there are no open file handles in the tmp jail because fuser is
designed to return exit code 1 in that circumstance.  So I've put a
guard on it which tests for open handles.  It will swallow fatal
errors as well - but the user should find out soon enough from other
commands. :-)

It was tested by the build for the ckermit patch.
