First off, excuse my ignorance of much of yum and python. New
territory for me.
I'm investigating use of yumdownloader to marshall a coherent set of
RPMs for a small CentOS based iso image. Although my target is
CentOS5, my development platform is FC6, so I started with yum-3.0.5-2
and yum-utils-1.0.3. I was able to patch yumdownloader to take a
--installroot arg (see end of post).
This gave me something that ran, but not to completion:
$ ./yumdownloader-1.0.3 -c yum.conf --installroot installroot
--destdir RPMS.x --resolve bash

This patch to /usr/lib/python2.4/site-packages/yum/packages.py fixed
that little problem:
def __eq__(self, other):
# if other == None:
# return False
if comparePoEVR(self, other) == 0 and self.arch == other.arch
and self.name == other.name:
return True
return False
OK, now it runs, but it doesn't "resolve" a very complete RPM set:
$ ls RPMS.x/
bash-3.1-16.1.i386.rpm
$
No glibc, etc.
So now I'm trying again, but with yum-3.1.6 and yum-install-1.1.2. I
now find that yumdownloader requires various things to already exist
in the installroot which it was happy and able to create in the
earlier version. Specifically it expects the installroot to already
include an rpmdb and cache directories for each repository (both of
which I've found workarounds for), and then also demands to find a
pre-cached repomd.xml file per repository.
Are these intentional changes of behaviour, or are they regressions
which I can help to debug?
This is not intentional :-)
Here's the --installroot patch for yum-utils-1.0.3:

yumdownloader in yum-utils 1.1.x has been redesigned to inherit to
options from the yum-cli, it look like it have introduced some regressions.
You installroot patches look fine to me, if no one have any objections,
i will add the patches.
