You should use one of them - not both. > > Further reading indicates that cvsuping with RLENEG_4_9 will update only > critical items.

Either RELENG_4 or RELENG_4_9 will get you complete sources. The differences is that RELENG_4 is the development branch leading up to the next 4.x release, while RELENG_4_9 is essentially 4.9-RELEASE + critical fixes. (With 4.9-RELEASE being essentially a snapshot of the RELENG_4 branch at a particular moment in time.) RELENG_4 can potentially contain a large number of differences from 4.9-RELEASE, while RELENG_4_9 will only have minor (if any) differences to the sources used for 4.9-RELEASE. > > Thanks for your patience with this.

RELENG_4_9 is much less likely to introduce *new* bugs to the code, but it will not get all the bugfixes or new features that get added to RELENG_4. Most of the time RELENG_4 (aka 4-STABLE) is quite stable and safe, but occasionaly things break badly. (An example of that is back in August 2003, when RELENG_4 was quite unstable and crash-prone for a period of about three weeks, until a bug had been fixed that had been introduced when support for machines with more than 4GB RAM had been added.) If you currently do not have any problems with 4.9-RELEASE and follow the "if it ain't broke don't fix it" school of thought then RELENG_4_9 is probably right for you. Personally I use RELENG_4, but then it is not crucial that my machines stay up all the time, so if they crash due to some new bug introduced in RELENG_4 it is not a major catastrophy. -- <Insert your favourite quote here.> Erik Trulsson [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
