Thanks Jonathan and Colin,
Both solutions work in the longer term, but not during the initial boot.
Custom %post scripts, (with or without nochroot) happen after the
Spacewalk created %post, and the rhn_check is in that section. So
rhn_check hangs for several minutes trying the remote repos.
I've come up with a dirty hack that seems to work.
Looking at the order that Spacewalk 0.6 puts the various %post sections
into the Kickstart. First we have the %post --nochroot section that
contains both the Spacewalk inserted and the user edited sections (in
that order), then there is the Spacewalk %post section, and finally the
user edited %post section.
I created a %post --nochroot script that contains the following lines
%post
rm -f /etc/yum.repos.d/*.repo >> /root/ks-hack.log
Spacewalk addends these to the %post --nochroot section, creating a
third %post section that gets run before the Spacewalk %post section.
The repos get deleted before the rhn_check runs, and it sails through in
0.041 seconds (it tells me) rather than the >10 minutes it took time out
before.
This is a dirty, nasty hack, and I am sure that something will break it
at some point.
Can anyone think of a more robust solution?
Actually, my solution is slightly different than I'd just implied:
Here's my %pre script that sorts this out, taking advantage of default
spacewalk behaviour later on to make this do something useful:
mkdir -p /tmp/ks-tree-shadow/etc/yum.repos.d/custom
cat << EOF > /tmp/ks-tree-shadow/etc/yum.conf
[main]
cachedir=/var/cache/yum
reposdir=/etc/yum.repos.d/custom/
