looks OK for now, I'd wait a bit on upstream commentary as I didn't
plan to bump ifudown2 really soon, so maybe I can just pull the master,
or even the current release, as the last one was almost half a year ago,
so one should probably happen quite soon anyway. Or aren't they
motivated at the current time as of Debian's freeze for Buster?
At least Julien Forint is the DM of the package[0] and the releases
have a almost suspicious high frequency just before the freeze kicked
in ^^

Anyway, I hope I do not hinder you here? I'd try to at least bump it
once for our PVE 6 release (whenever that is) on current master.
