Great, unless Gerard has any other reasons we will hold @ 2.4.3 for a
while. We'll have to update the profile we have now, but I don't think
the 2.4.2->2.4.3 changes were that big.

Agreed, unless Gerard/others have a complaint I think we should
do it this way. Chaps and a main profile.

Well thats still up in the air, but the two things I think that would be
important would be
1. the messages are all in some xml format.
2. we allow for some ability to add infrastructure later on
(I am think authentication/authorization type features that
might depend on the front-back end setup.....)
Other than the authorization/authnetication and I guess encruption type
issues, the front/backends should be able to parse and deal with the
xml message itself.... Also we might want to look @ jabber.org some
more as although it is based on IM type clients, they are providing
such a messaging infrastructure that we can probably use, is already
more robust, gives us their extra IM/other features, etc......

Yes this is a good idea, and I think we should go breath some life into
the ALFS-IPC list. Neven do you want to do the initial post, and maybe
do a smaller cross post to alfs-discuss, lfs-discuss(?)? Something to
breath life into it? Gerard, suggestions?

Well go take a look at the general descriptions of something like XSLT
and how we can use it to make xml act as a database on a system locally.
Also think about having say a cpan type setup where you can always get
a local mirror that has all kinds of program profiles in them, maybe even
the program tarballs themselves. Dunno if we need to re-create some of
these already established ftp archives. Maybe add some xml messages
between the infosystem and someone's alfs to figure out details, profile(s)
needed etc. Start throwing in LFS-hints and other such things to add to
the expierence, make it work right or manually etc.

Heh, nice. Thanks, I had not done it. Just got the idea....
Send it whenever.

I will test and verify this as I get back to alfs, just now getting back and
<chroot/package location mess snipped>

I'll put some more creative energy into it. :)
/me hopes he doesn't draw a blank...

Yes this is what I mean. Sure we can do it in system command, but we
can do configure there also, but we are not and I think it would be a
good idea to decide on new tags whenever something is used alot, with
the rest being left for system command kludges.
> Why <builddir>? What's wrong with "builddir" as a <package> attribute?
same reason as the <patch> one, no other. Why not as an "named" attribute,
as I don't know if it is used enough, like only really two packages use the
technique, and it seems to be more like the
type concepts we made than an attribute.

Yes agreed, I want to start submitting all this to cvs, but wanted to get a
basis of agreement here first.... Since it was changing alot.

thx, they were fun, and yours?
who is Sore Loserman, I want him for president :)
