Re: [K12OSN] Release cycle too fast



I realize that I'm asking for a lot, and I don't want
it interpreted as me being ungrateful.  I'm just
trying to give input from the point of view of
somebody who is primarily a user, and not an
administrator.

I realize that I can manually install packages, and
even source if I need to.  I've done it before, but
one of the really great things about linux is the
automatic dependency-checking installers like apt,
yum, urpmi (for Mandrake).  But keeping an old system
up to date without that would mean being on an email
list for every application that the old system runs so
I could keep informed of security updates.  

Thanks for the explanation of applications, libraries,
etc.  I'm still a bit confused about it.  I don't
understand why this situation is not possible:  I'm
running FC1.  Application "xyz" needs updating, but no
packages are available because FC1 is unsupported. 
yum xyz2 to get the updated package from the FC2
repository.  But xyz2 requires abc version 2.  My
system has abc version 1.  yum uninstalls xyz1,
uninstalls abc version 1, installs abc version 2, and
installs xyz.  Of course, it also has to take into
account what else depends on abc version 1 and upgrade
that to a version that can use abc version 2.  It gets
complicated, but isn't that what these packaging
systems are supposed to do?  Conceivably, with enough
updates, my FC1 system could become FC2.  At least
that's the way it seems to me, so tell me why I'm
wrong.  (I'm sure I am, otherwise we'd already be
doing it that way).
