• Barry Kauler ☛ woofQ2 now generates devx sfs

  I recently posted some pictures of the structure of woofQ2:

  There is a fundamental problem with the pups and pup-derivatives and pup-lookalikes; that they use a aufs/overlayfs layered filesystem, which traditional package managers such as APT do not recognise.

  The "devx" squashfs file is an example. It has lots of packages. APT/dpkg maintains a database of installed packages in /var/lib/dpkg; in the case of EasyOS, that will be in the bottom layer, easy.sfs. Then you want to compile a source package and bootup with the devx .sfs layered on top; how can APT/dpkg be informed that there are a whole lot of new packages installed? Unfortunately, it is not a simple matter of having another layer of /var/lib/dpkg in the devx sfs.
