Could you explain that a bit more. Sounds like you saying it's worth messing with the flamebox scripts to use git instead of using the git cvserver and letting them pull the cvs branches as they do now. Is the existing flamebox email of build log effected buy switching form cvs to git? I hadn't expect it to change. > Besides that, it's not a black-and-white scenario.

I get the impression your suggestion to first get git-cvsserver serving the repo so that the build machines works without any change and then to go to each build machine and update the scripts to use git instead of cvs. Are there any tricks I need to so on the repo to make the branches pull out with exactly the same commands that we are currently using. My guess is that the branch checkouts should work without any messing around. > > Just my two cents. Hey, you two cents could easily save me hours of messing getting this conversion done. BTW, I don't think anyone is checking into the repo, but if they do can I do another git-cvsimport to just update the one I already did? - -piet -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHGHUUJICwm/rv3hoRArHsAJ9GQMjpLc5CzpBXnHkxLfBgfwEo/QCdGNfj DiivgfDDSbIB+9YBZvj/5Z0= =SBSg -----END PGP SIGNATURE-----
