Hi,
we need to install multiple kernels per system and instead of relying on
sysinstall (I couldn't figure out, how to install multiple kernels with
it, especially since it wants to install the default kernel to 'kernel')
I hacked up my own kernel installation
I'm using a Makefile to drive our release and package building and for
the releases I'm using an install.cfg, which gets created on the fly,
since the names of the kernels change now and then, here is the release
target
KERNELS= SERVER GENERIC SMP
release rerelease:
# Write automation script for sysinstall
rm -f ${TLR}/usr/src/release/.install.cfg
for k in ${KERNELS}; do printf "%s\n%s\n" "command=/bin/sh -c \"cd /dist/${RELEASE}/kernels && ./install.sh $$k\"" "system" \
>> ${TLR}/usr/src/release/.install.cfg; done
sed '/^#KERNELS#/r ${TLR}/usr/src/release/.install.cfg' files/install.cfg > ${TLR}/usr/src/release/install.cfg
cp files/src.diff ${TLR}/usr/src/release/src.diff
# Create a src patch for our kernels on the fly, so we can pass it to make release
(for i in ${KERNELS}; do diff -u /dev/null kernels/$$i 2>/dev/null || true; done) | sed 's,kernels/,sys/i386/conf/,' \
> ${TLR}/usr/src/release/kernels.diff
# Copy them over again for rerelease, perhaps something changed
.if make(rerelease)
.for k in ${KERNELS}
-cp kernels/$k ${TRR}/usr/src/sys/i386/conf/
.endfor
.endif
cd ${TLR}/usr/src/release && make ${.TARGET} \
BUILDNAME=${RELEASE} \
CHROOTDIR=${TRR} \
WORLD_FLAGS="-j4 \
MODULES_WITH_WORLD=yes \
WITHOUT_MODULES='3dfx 3dfx_linux ath ath_hal ath_rate_amrr ath_rate_onoe ath_rate_sample aue\
bktr cardbus coda coda5 dcons dcons_crom fatm firewire firmware harp hatm \
if_ndis ip6fw ipw iwi joy kue ndis pccard ral splash syscons umodem ural urio\
uscanner utopia uvisor wi wlan wlan_acl wlan_ccmp wlan_tkip wlan_wep wlan_xauth'" \
KERNEL_FLAGS="-j4 MODULES_WITH_WORLD=yes" \
KERNELS_BASE=''\
NODOC=YES NOPORTS=YES NOSRC=YES NO_FLOPPIES=YES \
RELEASENOUPDATE=YES \
LOCAL_PATCHES='src.diff kernels.diff' \
KERNELS='${KERNELS}' \
CVSROOT=${CVSROOT} \
CVSCMDARGS='${SRCDATE}' \
RELEASETAG=${SRCBRANCH}
cd ${TRR}/R/ftp && find -d . | cpio --quiet -dumpl ${TFR}
And files/install.cfg contains the following
debug=yes
mediaSetCDROM
# Select which distributions we want. We omit the kernels here, we do them by hand
dists= base doc manpages games catpages dict info
distSetCustom
# Partition Editor
diskInteractive=YES
bootManager=standard
diskPartitionEditor
diskLabelEditor
installCommit
# Magic marker, don't edit! Is set automatically from the Makefile!
#KERNELS#
# End of magic marker
So basically, sysinstall is intructed to not install any kernel, but
after all distributions are extracted the following commands are run
command=/bin/sh -c "cd /dist/${RELEASE}/kernels && ./install.sh GENERIC"
system
command=/bin/sh -c "cd /dist/${RELEASE}/kernels && ./install.sh SMP"
system
It has the nice side effekt of GENERIC and SMP landing in
/boot/{GENERIC,SMP}
We also ship a /boot/loader.conf that sets the correct kernel to boot
and is versioned and centrally controlled, yadda yadda yadda
hth,
