pacman -Q obviously not the answer, but whilst on that - is it possible to do a pacman -Q, save the output somewhere, then on another machine, just reverse the process? Would save me heaps of time putting a system back together as happened last week when i had to replace my HDD, taken me ages to 'remember' everything I had on it.

To save the download time, if the machines are the same architecture:
`pacman -Qq > pkg.list` then on the other machine
(as root) rsync -uav username@oldmachine:/var/cache/pacman/pkg /var/cache/pacman
`sudo pacman -S $(cat pkg.list)`
If you rsync (or scp or move with a usb stick) the package files from the oldmachine to the newmachine before issuing the "sudo pacman -S $(cat pkg.list)`, then the install uses the local files and avoid the time required to download them. You can easily do a 10 minute install that way.
as a small aside; after being corrected a few times on bbs, i now know that pacman -Qqe | grep -vx "$(pacman -Qqm)" > pkg.list and cat pkg.list | xargs pacman -S --noconfirm --needed work the best for this. list out only explicitly installed minus any foreign packages; then only install those that are needed (pull in your own deps). -- patrick brisbin
