[pacman-dev] feature request: pacman lock file

I have several chroot environments that all use pacman as their package manager. I use a shared /tmp directory between them, so that X applications and some other things work across the chroots. This however is a problem with pacman, since pacman puts its lock file in /tmp/, which means I cannot use pacman simultaneously in these chroots. It would IMO be a better idea to put the lock file in /var/lib/pacman/ instead, which ensures that the lock file and the pacman database are always tied together.
