This is not an acceptable solution for a desktop system.  Especially if there
is a seamless recovery that is both secure and does not even have to bother
the user.  The /tmp directory does get whacked quite often on some systems,
it is not part of any installation.  In any case, for a desktop system,
NOTHING should just print an error and fail hard unless there is absolutely
no possible recovery.  Things do go wrong in practice for whatever reasons,
and Joe User is not going to log in on a text console and read the syslog
with vi.

Nothing is guaranteed for /tmp, scripts regularly even wipe this directory.
/lib is completely different story.
