Well, can't we just STOP the non-sense of building images on Salsa all
together? This was an unilateral move of Waldi without any discussion,
even yet an approval, from the team. What we were suppose to do was
building the images on Casulana.
At this point, we see that it is bad in many regards, the most blocking
point being that it is impossible to save an artifact bigger than 256GB.
This prevents me from building an Octavia image, for example...

I don't think we need image as small as possible, to the last bits.
Quite the opposite, to make the resize-at-boot possible, we need to
leave a bit of free space. But even like that, we're talking about
saving half the space... That's half the storage space for providers,
for us, and many more (and also half the download time).

Why can't you keep the idea of just shrinking the filesystem instead?

You can, but I'll be on holidays, and not available.
I also would like to discuss (here) if we could move the regular meeting
time to business hours, because really, I hate the evening meetings
because either I'm busy, or I just forget. If I remember well, the
reason it was on the evening was because of Serpent, who's not part of
the team anymore. Is there anyone else for who a late afternoon (to be
US timezone inclusive...) meeting wouldn't be convenient?
Cheers,
