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
what you want to do? This is done in this way because we need a writable block device plus compression, this is done: [rw-fs] (ext4 /) -> [dm-snapshot] -> {ro-fs-loop} (origin) + {rw-cow-loop} (COW) {ro-fs-loop} -> [fs-image] -> [ro-sfs-loop] -> [sfs-image] -> [ro-fs] (iso9660 / extfs / vfat) {rw-cow-loop} -> [cow-image] -> [rw-fs] (tmpfs/non-persistent | extfs/persistent) -- Gerardo Exequiel Pozzi \cos^2\alpha + \sin^2\alpha = 1
