etcupdate does a 3-way merge of an "old" stock /etc and a "new" stock /etc into /etc. The "old" stock /etc is always stored in /var/db/etcupdate. The "new" stock /etc has to come from somewhere. One option is to generate it from /usr/src (e.g. after a buildworld). However, you can also pregenerate tarballs from a /usr/src tree on one machine and then use those tarballs instead of generating an /etc tree from /usr/src on another machine. I've used this for upgrades of a cluster of machines where a single machine would build release "images" that were basically a buildworld + an 'etcupdate build' from the corresponding src tree. I then used 'etcupdate -t /path/to/tarball' to update /etc after installing the new world. The idea is that for something like freebsd-update one could ship the latest etcupdate build tarball on each update to do a full 3-way merge of /etc. -- John Baldwin _______________________________________________ firstname.lastname@example.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
