# TODO left:
# * maintenance job needs to:
#   - cleanup the log files eventually
#   - check for running builds using systemctl show
# * logs should auto display in browser like with jenkins… (long-polling, meta-refresh, something)
#   - there's an NPH solution pointed out by Xtaran
# * translate yaml into a script or such to create those service files (done for i386 for now)
