Catalyst takes a tree snapshot (/usr/portage as .tar.bz2), unpacks it somewhere and bind mounts it to its workdir. I'd like to get rid of this step, since it takes lots of time and wastes lots of disk space. I'm interested, what catalyst devs will say about it. > > =E2=80=A2 (Squashfs seedstage support) > > Maybe the same is possible for stages?

You rsync stage1 to a workdir and build stage2 there. Therefore you have to unpack the stage1 somewhere and store it there.

I know, but i already know where to start, since i alredy got in touch with it last year.

Why, exactly? There are reasons like "mounting stuff", "creating /dev files" and others, but maybe we can do that without root... > > GNAP tasks: > >=20 > > =E2=80=A2 Code/Tree hosting, VCS > > I've done some work last year and that does only exist as some patche= s, > > since there is no central repository for GNAP development.

Maybe we could use the old tree, only fix security problems and ship that. Maybe we could package.mask it and use a development tree, that is only tested for building. Maybe some GNAP user (there have been some last year) is willing to share his tree and we can build on that. I'd like to look into an easy, mostly automated way of creating the tree, like a bunch of scripts and some documentation. If this is the only thing i get done, it was worth it. If i only get it started, then we are closer to being usable than we have before. > > =E2=80=A2 Reimplementation in python research > > Catalyst is written in python, maybe we could make better use of it i= f > > we reimplemented some parts of GNAP in python?

It's only research. There were some things i did not like in gnap, but i saw no other way to do it in such a low level language as bash. If i can do the scripts with half or one third of the lines of code in python, i would do that. If gnap and catalyst would merge in a way, that catalyst provides the tools and gnap only very very simple scripts and resources, that would be perfect, but gnap should not handle overlays, configurations and stuff, it should just pass them to catalyst. Much easier to do there, i think. But again, that are my current thoughts. Philipp --=20 gnap-dev@lists.gentoo.org mailing list
