Note that there is no way to avoid having userland and kernel out of synch temporarily during the update. More important, in general, is making sure that the new system kernel is capable of booting before you go ahead and replace the rest of the base system. -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

This is what I did (roughly out of my head): 1.- synch your source to 6.1 (or whatever) 2.- make buildworld 3.- make buildkernel 4.- make installkernel 5.- sh /etc/rc.shutdown # kills all your services 6.- pkill sendmail 7.- pkill syslogd 8.- mergemaster -p 9.- make installworld 10- mergemaster # this one is a lot of fun, be careful 11- make delete-old # this one is breath-taking 12- reboot # best suspense ever 13- make delete-old-libs With mergemaster, make sure you read and understand everything.

Rebuilding, Got Questions
Hi; The box I've taken over has BSD 5.3 so I need to upgrade. This is a big jump and the console is half a world away so I have some questions: * Can I do all of the steps of the installation without reverting to single user mode? * Where do I find the src to download?? All I find are ISOs. Is there no *.tgz file anywhere? * I'm upgrading from 5.3 to 6.1. Will I have to run mergemaster -p before running buildworld? Do I need anything more in /etc/make.conf than the following? CFLAGS= -O -pipe NO_BLUETOOTH= true# I have no need of this NO_SENDMAIL= true# I use qmail The current /etc/make.conf has this and I don't understand why: # -- use.perl generated deltas -- # # Created: Wed Dec 21 21:11:27 2005 # Setting to use base perl from ports: PERL_VER=5.8.5 PERL_VERSION=5.8.5 PERL_ARCH=mach NOPERL=yo NO_PERL=yo NO_PERL_WRAPPER=yo Should I leave the above? Merge the two? Throw out the above and just use what I've written (above that)? Will that screw up the installation? Will that screw up perl? Here is my procedure.

Re: Rebuilding, Got Questions
You should cvsup to update your sources. I believe it is recommended you first update to 5.5, then update again to 6.1. Once you cvsup read the UPDATING file in /usr/src. I would be wary of using the -j4 it has caused some issues, check UPDATING before using that flag. -Derek At 01:44 PM 8/15/2006, beno wrote: Hi; The box I've taken over has BSD 5.3 so I need to upgrade.

Not sure about perl, I only have PERL_VER=5.8.8 PERL_VERSION=5.8.8 on 6.1 Here is my procedure. Look good? I'd recommend to first rm -rf /usr/obj/* to be sure you don't have any stale object files, and copy your old kernel to another name so you can revert back to that known one at any time. cd /usr/src make -j4 buildworld // single CPU system make buildkernel make installkernel reboot I wouldn't do this, because after reboot your kernel and userland are sure to be out of sync and that may cause problems preventing you from fully (multi-user) booting. Or what if the rc scripts have changed (but not installed yet) and your NIC doesn't come up because of that... If you are willing to risk not rebooting to single user, then don't do a reboot after installkernel. Instead, first (optionally but recommended): mergemaster -p p means preen mode, for when for example a user and group needs to be added to your user database. You want to use this before installworld (or skip it and pay attention to /usr/src/UPDATING and while running mergemaster after installworld). make installworld mergemaster -p without the -p. Should you need to merge some config files, press l to keep the left sided line/version, r to keep the right sided. reboot The above recipe (with or without mergemaster -p) is what I've been using for as long as I can remember. It's pretty safe and if you don't have a serial console hooked up at your remote site, it's probably the best you can do. (also shut down all services except ssh before installworld). Well, if you're experienced and not too whimpy you *could* also use the dist tarballs from a recent install CD, extract them or copy first then juggle with some mountpoints to see if anything breaks, go back and forth a bit if needed... so you'd replace your /bin, your /sbin, .. etc, one by one and in the end reboot.

Your update procedure is fine. For the use of mergemaster, you many want to see FreeBSD 6 Unleashed by Michael Urban and Brian Tiemann the 2006 version. I have found the mergemaster instructions to be somewhat confusing. Make sure you have a backup or atleast a disk image.
