That would mean mgaapplet would have to regenerate initrds etc. at the
end of the process too as various packages have code that prevents
initrd generation during install (this was most recently highlighted due
to a bug with this check in mageia-theme breaking btrfs installs in the
installer - still need to do an official update for mageia-theme so that
at least net installs for btrfs+mga2 work).
