This moves any perl files into bin and sbin folders which will be directly installed in /usr/bin and /usr/sbin. This is done such that the extract modes in list.xml still work and the files end up in the right places. All other files have been moved into the tree folder in their final destination.
This commit converts the rescue system to systemd rather than the legacy sysvinit. Besides being faster, one primary advantage of running systemd here is that we can "boot" the system we're inspecting via systemd-nspawn to properly test it. Note: Bits that don't work: * nspawn * old dracut initqueue udev rules in /etc/ are not cleaned out (drop in support error?) * the gui may loop differently now
We can easily avoid post processing the tree simply by moving the tree around and ensuring we set it up correctly (with the compat symlinks) early in the process.
The main change here is not remounting a fresh /run. Dracut does this for us and we actually need to keep this one as the initial udev database (when udev is started by dracut) is stored here and thus mounting an empty fs could see us lose some metadata. We no longer touch the /bin, /sbin or /lib[64] symlinks as these are already relative symlinks into /usr and simply bind mounting /usr is enough.
