This is *WRONG*, it will also return 0 if /tmp is not a symlink.

(Also, use test -h instead of test -L for symlinks, cf. the
GNU autoconf texinfo manual, *Limitations of Builtins::)

What about this instead:

	if test -h /tmp; then
		# symbolic link
		# will be created by mount_tmp if it does not exist
		test -d /tmp || return 0
		# but we’ll clean it if it does
	fi
