Which is better? Why?
I know yum is the official update mechanism here and in Fedora Core, but
that doesn't make yum better than up2date any more than Windows NT was
better than OS/2.
Let's try to keep the discussion objective:-)
I'm asking, hoping for some insights into why RH might (apparently) be
moving to yum in preference to up2date (yum is now used within Anaconda).
Other than general discussion, I'd also like to know what I'd muss by
using up2date on CentOS.
I'll start with this:
What has yum that provides this functionality:
up2date -d -u
The up2date that is used in CentOS is not like the up2date for RHN ...
it is in fact a bastardized version of old (2.0.x) yum repos. There are
backend repos that are not nearly as polished as RHN for yum and repomd
in up2date. The up2date for RHN is as good as yum ... however the
up2date using yum repos is not nearly as good. For example, obsoletes
did not work until we fixed it in the 4.4 update.
Where does the up2date in Fedora Core 3 sit in this?
I am currently working on the yum-plugin-downloadonly to address that
specific issue.
Does it get source too? That's about third on the list of things I like
to do.
Up2date also can not use the mirrorlist option which provides 10 GeoIP
based mirrors that failover based on (if you install the fastestmirror
plugin) speed.
I really don't like the mirror list I've seen in Fedora Core. It pulls
stuff from all over, Europe, Middle East - mostly, it seems, about as
far away from Western Australia as possible.
I prefer the Debian approach; I choose a mirror. In Australia, IAPs
commonly have a peering arrangement; content from within the peer
network isn't charge against download limits. While (AFAIK) all members
of WAIX (the local peer network) are in WA, not all IAPs in WA are members.
Up2date does not have protectbase or priorities capability.
Up2date does not have a GUI capability like yumex.
I've never used yumex, do I can't tell whether up2date's GUI capability
is like yumex's.
yum is MUCH better than up2date for CentOS.
As I mentioned elsewhere, installed 4.3 just before 4.4 came out. I'd
uch rather have downloaded the packages overnight (triggered by cron)
than type the commands in through my modem line.
GUIs aren't very good through modems.
