If you have a private CVS repo mirroring the FreeBSD tree then you can keep your changes up to date in your "checked out" source tree. but you can generally not check them in anywhere. You CAN keep your own special branch (I think it was branch numbers above 100000 or something, check cvsup docs) that cvsup will not over write, and you can check in your changes there but that branch will not automatically update from freebsd.org so you will need to do branch updates regularly. (and that can be tricky and time consuming in CVS) otherwise your branch will get out-of date when compaerd with -current. usually I just keep my work checked out until I'm ready to feed the changes back but I take regular diffs and stash them away as 'backups' :-) This is why we have the perforce repo in addition to CVS. it is good at doing large branch manipulations, and it is more feasible to keep your own branch in sync with the branch that is kept up to date with the CVS tree. Unfortunatly, we don't give out access to that to 'anybody', it may be possible to get mercurial to do similar, or if you could get a 'personal use' p4 server you could get the scripts from Peter and see if you could do the same. I wonder if ther is a way we could broadcast changes to the p4 'head' branch so that people could keep their own p4 servers up to date.. > etc... > > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org"
