This test failed on non-Linux systems: - On Solaris 11, the output of the native df(1) tool has a different order, and hence the detection of a usable mount point for the test fails. Verify that df(1) is from GNU coreutils, or fall back to 'gdf', else skip the test. - On a FreeBSD system where /home was a symlink to /usr/home, the code for finding a usable mount point failed, because the symlink itself is on the '/' file system. Ensure that the found mount point is identical to the original test directory like /home etc. * tests/find/mount-vs-xdev.sh: Try harder to use a GNU df(1) tool. Check whether the found mount point is identical to the original directory name, thus avoiding symlinks.
