[sane-devel] qcam: Avoid creating lock file in /tmp/

[wls at astro.umd.edu]

> Looks ok. Are you sure that /var/lock is available everywhere?

Solaris doesn't have it.

Aren't special privileges required to access the /var/lock directory?

	# ls -ld /var/lock
	drwxrwxr-x    6 root     tty          1024 Mar 27 04:02 /var/lock

setguid tty, at least, is required on this system (Mandrake 8.0).  I remember
when /var/lock was introduced (showing my age) to help uucp coordinate the use
of the modem lines with dialout programs like cu and tip.  I remember the
security issues and contortions with tip then because it had to then be setgid
uucp to handle the lock file.
