Keeping src up to date

(Re)build a custom Kernel

1. Make sure we have latest sources

$ cat src-supfile

*default tag=RELENG_9
*default host=cvsup3.uk.freebsd.org
*default prefix=/usr
*default base=/var/db
*default release=cvs delete use-rel-suffix compress

src-all

$ sudo cvsup src-supfile

RELENG_9 is the STABLE release of FreeBSD. We shall stick with that.

We want to (we should never not!) build the kernel and the “world” (userland) from the same src update.

2. Read /usr/src/UPDATING

less /usr/src/UPDATING

Honestly, it is worth it. The times I did not bother, of course the
thing I cared about was right there in UPDATING.

3. The run through (from my OSBuilder code)

   echo `$dd` start makeworld >> $log
   echo NO_PROFILE=true >> /etc/make.conf
   cd /usr/src
   make -j6 buildworld
   
   echo `$dd` start kernelbuild >> $log
   cd /usr/src
   make buildkernel KERNCONF=GENERIC
   make installkernel KERNCONF=GENERIC
   
   
   echo `$dd` start installworld >> $log
   cd /usr/src
   echo make installworld
   make installworld
   echo now run mergemaster
    #run so that it automatically installs new config files, and puts any diffs into /var/tmp/temproot.xxx
   mergemaster -ia
   

4. do the above, manually ...
