This has been annoying people for quite a while, but I'm don't think anyone's filed a bug on it. We need a bonsai "tree" for the 1.8 branch and one for the 1.8.0 branch so we can set open/closed state on those branches. I don't currently see one in http://bonsai.mozilla.org/switchtree.cgi (Once we have one, it's pretty easy to edit the tinderbox configs to point at the appropriate tree -- I think it's even be doable from the tinderbox UI, but I'd honestly guess that that's riskier.)
Looks like in order to add a tree to bonsai, I need to match it to a module in CVS. Can you run cvs co -c on the cvs server and tell me if any of the existing modules are appropriate? The Seamonkey 1.0 Branch tree uses MozillaBranchTinderboxAll, which appears to only differ from MozillaTinderboxAll by the addition of NSS and NSPR. Is that one appropriate to use, or do we need to create another one?
The module to use is AviarySuiteBranchTinderbox.
OK, this is done. Find me or file another bug when you want to mess with Tinderbox.
