Re: Using .tar.xz only on (was: install-module / /

Sorry Olav,

I thought this is actually going to happen soon and the decision was
set in stone.

Basically most distros won't ship it by default, at least not for now.
Solaris/RHEL/SLED/CentOS are probably the worst cases here. But also
custom environments (we are talking about things like glib heavily
used in embedded...).
I'm not saying these are showstoppers, I am saying that we should give
them some time to adapt, try to encourage Fedora/OpenSuSE/Ubuntu to
ship lzma by default would be a good starting point. Letting the
enterprise guys at least provide packages/repos for it would be nice
as well.

It is true that people using packages more heavily are the distros and
jhbuild-ish setups, but they automate their infrastructure in a fixed
setup anyway so they are not the ones we should worry the most. I'm
thinking about the casual people trying to build a given tarball from
some platform and not being able to. Maybe we should actually make a
difference between packages from the desktop release set and the
platform/development ones in this regard? (i.e. shipping bzip2/xz for
things like glib/gtk/vala/gjs and just xz for cheese/gnome-shell/...
and personal projects?

Do you think having a .bzip2/.xz transition time would make sense or
make things any better? Say dual during 3.0 and just .xz for 3.2

Yup, sorry, I thought you were going ahead actually. :-)

6 seems a reason not to :-)
