The patch for the spacewalk.git/hooks/update file
hooks-update.diff

attachment
update-new.diff

I've made the changes, however the version of git on the hosted server is older than the one you used to create that patch so I applied the original patch to the update hook on a fresh git repo on my F-9 desktop and uploaded it to the hosted server. The original update hook was saved as update.orig. I've attached a diff of what used to be in the hosted spacewalk repo and what's there now.

Note sure if this is related but I'm now getting this error when attempting to push changes:

I have confirmed other developers are getting rejected with the same error.

The update hook has this bit of code in it:

# check for no description
projectdesc=$(sed -e '1q' "$GIT_DIR/description")
if [ -z "$projectdesc" -o "$projectdesc" = "Unnamed repository; edit this file to name it for gitweb." ]; then
echo "*** Project description file hasn't been set" >&2
exit 1
fi

I set the description to "Spacewalk is an open source Linux and Solaris systems management solution." That should hopefully fix it.

That did the trick, thanks!
