Debian Unstable vs. Ubuntu

Wed Feb 9 01:08:58 UTC 2005

Well, to sum up:

- If Ubuntu and Debain are in fact working in a similar fashion to the
way *BSD coordinate their work, then that's probably the best model.
- I got the impression of duplicate work from Ubuntu's separate
repository. I would've rathered seeing a certain patch system to
Debian that converts Debian to Ubuntu. But then again, you just
clarified the goals of Ubuntu (to make a coherent,  "apt-to-date", and
a secure desktop/server distro), which I think Ubuntu has so far
accomplished. I'd like to see one thing though, more frequent updates
to stable, I don't think I'd like to see Ubuntu ending up with the
same reputation as Debian's stable being "dead", as in, living way in
the past.
- Agreed, merging distros is a bad idea, give us choice. But on the
other hand, I don't like seeing way too many options too choose from
(as a user/sysadmin), since in most times this creates unbearable
diversity.
- I'll be more than glad to help out with Ubuntu's documentation, or
for the matter any other projects, since I loved it so much, hopefully
I'll be able to free up some of my time. I think I already mentionted
that the only distro that really caught my eye and quickly became my
favorite is Gentoo (aside from my favorite FreeBSD, but that's not
Linux). Ubuntu proved itself to be a great system, and now I have 3
very nice different choices.

I think that clarifies my concerns, and I'm very happy we all had this
conversation, I'll probably convert it to a longer blog post and
announce it on this mailing list, since I had many people already
asking me about Ubuntu vs. Debian.

So, thanks again :)
