Fedora template update: automatically reinstall custom user rpms

[rootkovska]

For users upgrading their original Fedora templates (which don't have any custom repos added), it's easy to retrieve and "play back" the list of all custom RPMs installed:

[user@fedora-23 ~]$ sudo dnf history userinstalled | sed -re 's/^(.*)-([^-]+)-([^-]+)$/\1/' | tail -n +2 > pkgs
[user@fedora-23 ~]$ qvm-copy-to-vm fedora-24 pkgs
[user@fedora-24 ~]$ sudo dnf install -y `cat ~/QubesIncoming/fedora-23/pkgs`

Of course the above doesn't take into account any non-RPM-packaged template modifications (e.g. custom /rw/config/), nor RPM packages from other-than default YUM repos.

Still, I think somehow aumating the above would be helpful for many users. It's not clear to me, however, UI-wise, how this automation should be done to be most useful and easy to use? I.e. who should offer to run these scripts?

Interesting. But I was thinking about something totally different: install additional packages using salt stack. This way, you can easily redo the operation on any other template. Also, I think if someone want to preserve as much as possible - can simply upgrade the template in-place. If someone want to "refresh" the template, probably want to review the list anyway (and not install no longer used tools). So the above command IMHO should just go somewhere into documentation. BTW - slightly simplified command: sudo dnf history userinstalled | sed -e 's/\(.*\)-.*-.*/\1/' | tail -n +2
