Well, I'm not sure how to get the info out of the internals of portage itself (I have to imagine it would be fast since portage has to know about it already), but for a list of packages you can xargs them into qlist to get a list of all files, and then pipe that into a script that will populate a chroot for you. Quick script for those curious to try it out: mkdir newroot mount -t tmpfs none newroot cd newroot unshare -m /bin/bash echo "list of packages" | xargs qlist | linkfile (poke around) exit (note that bind mounts are gone) cd .. umount newroot ; rmdir newroot (note that all traces gone) Contents of linkfile script: #!/bin/bash install -D /dev/null "./$1" mount -n --bind "$1" "./$1" (That -n is important if you don't want to muck up your /etc/mtab ) BTW, unshare is a fun command to play around with if you've never used namespaces. You can do things like replace commands by bind-mounting right over them. Rich
