[arch-releng] squashfs

This is more likely not the correct place to ask, but I am interested in finding out more about mksquashfs. Currently I notice that root-image.fs.sfs once mounted gives root-image.fs which then also has to mounted [looped]. Is there a way to only mount and copy once? The root-image. Have noticed that some other live isos only need to copy out image to new install. MrG
