When we are attempting to create directory somewhere in the bowels of /var/lib and get an error that it already exists, it can be quite hard to diagnose what is wrong (especially for a user who is not aware that the directory must have the specified owner, and permissions not looser than what was requested). Let's print a warning in most cases. A warning is appropriate, because such state is usually a sign of borked installation and needs to be resolved by the adminstrator. $ build/test-fs-util Path "/tmp/test-readlink_and_make_absolute" already exists and is not a directory, refusing. (or) Directory "/tmp/test-readlink_and_make_absolute" already exists, but has mode 0775 that is too permissive (0755 was requested), refusing. (or) Directory "/tmp/test-readlink_and_make_absolute" already exists, but is owned by 1001:1000 (1000:1000 was requested), refusing. Assertion 'mkdir_safe(tempdir, 0755, getuid(), getgid(), MKDIR_WARN_MODE) >= 0' failed at ../src/test/test-fs-util.c:320, function test_readlink_and_make_absolute(). Aborting. No functional change except for the new log lines.
