Editing Jail Server Install (section)

= FreeBSD 6.2 -> 6.3 =

Last updated 2008-08-07

<pre>

1. remove old src
cd /usr
rm –fr src/*

2.  get latest sources for this release:

cd /usr/src 
echo "*default host=cvsup4.freebsd.org\
*default base=/usr\
*default prefix=/usr\
*default release=cvs tag=RELENG_6_3\
*default delete use-rel-suffix\
*default compress\
src-all" > sup

cvsup sup ; pagedave
(20min)

3. configure new kernel. Get config from similar machine or there may be a master copy somewhere under /mnt/data4/build/freebsd (name the kernel config the same as the jail, ex jail18):
cd /usr/src/sys/i386/conf 
scp backup2:/mnt/data4/build/freebsd/kern_config-6.2 ./jail7

or for PAE

scp backup2:/mnt/data4/build/freebsd/kern_config-6.2-PAE ./jail7

edit the kernel config and change ident to be the name of the jail:
vi jail7
ident           jail7

edit /sys/conf/newvers.sh to add –jc1 to the end of the BRANCH string (RELEASE-jc1)
vi /sys/conf/newvers.sh

3. bring over patches from backup2

The various patches are in /mnt/data4/build/freebsd/patches on backup2. There are dirs for each version. Not all dirs are populated, but patches for later versions work on older ones unless there is a new patch in the older dir.

cd /usr/src
scp backup2:"/mnt/data4/build/freebsd/patches/6.x/*" .

Apply patches:
patch -l < jls-patch

Apply these only to 2950 with PAE:
patch -p0 < gvinum-staticcompile-patch
patch -p0 < gvinum-bin-patch

4. build, install kernel
cd /usr/src
make buildkernel;  pagedave
(2min)

cd /boot
mv kernel.old kernel.old.old
(optional move old kernel out of the way)

cd /usr/src
make installkernel

cd /boot
mv kernel.old kernel.6.2


5. take ½ of mirror and test (boot up) in new hardware

6. improved loader configs:

/boot/loader.conf:
console="comconsole,vidconsole"
boot_serial="YES"
boot_multicons="YES"

7. build userland
cd /usr/src
make buildworld; pagedave
(33mins)
make installworld 

mergemaster –i
reboot
8. patch jail against starting jails with rtprio

mv /usr/sbin/jail /usr/sbin/jail_
echo '#\!/bin/sh\
/usr/sbin/rtprio -t /usr/sbin/jail_ $*' > /usr/sbin/jail
chmod +x /usr/sbin/jail
