How about requiring the user to touch some file in / or /boot which indicates the branch-tag that's acceptable for installworlds? Then you just need to propagate the tag from the 'cvs co' stage to some file under /usr/src (such as /usr/src/CVS/Tag ). So, maybe compare /usr/src/CVS/Tag to /boot/BRANCH_TAG, where the second file has to be typed in by the user, by hand. Eh, maybe /boot isn't the right place for it. Well, maybe /.branch_tag >[1] Guess who just trashed a stable installation for the 3rd time > in 3 years today? Well, I almost would have done the same thing in my latest 4.7 install, but when I cd'ed into sys/i386/conf I thought it was odd that there was a GENERIC.hints file sitting there... If it wasn't for my desire to compile an SMP kernel instead of GENERIC, I might not have noticed until it was too late!! -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
