The error message from mount, as well as the saved syslog file might
have some clues, but perhaps you haven't installed portmap (or haven't
started it)? You will also need nfs-utils, and I've seen
recommendations to use the "-o nolock" mount option in %post.
That was useful around the time of RHL 7.x or so, I don't know that it
still applies, and it's a long time since I used nfs for a ks install, I
use http these days.
If this all still fails, I'd suggest to break out into a shell in the
"fail" tree of your %post, to allow you to do some debugging.
Something like
chvt 6
/bin/bash -i </dev/tty6 >&/dev/tty6
Well vt 6 is where the installer X server seems to run but yes. I'm
afraid I copy openvt onto the box during %pre so things in %post (etc)
can use it - it is a cleaner tool. (note that the sl5 busybox includes
an 'openvt' but that doesn't have the useful options).
chroot ... openvt should work for any recent release.
In the %post remember that the startup scripts havn't been run so files
like resolv.conf may not have sane contents.
We use "%post --nochroot" so we can first copy bits of state (stuff we
saved from any previous install, the ks files and logs from the install)
into the newly installed tree, and then mount a directory from which we
run various scripts in the chrooted tree:
...
# location of new root
NR=/mnt/sysimage
...
## Get dns lookups working enough to do the first mount (sigh...)
cat > $NR/etc/resolv.conf <<EOF
..... <put your contents here> .....
EOF
## Fix up nsswitch.conf so host name lookups use DNS not try to use NIS
cp $NR/etc/nsswitch.conf $NR/etc/nsswitch.conf.SL_orig
printf "/^hosts:/\ns;:.*;: files dns;\nw\nq\n" | ed $NR/etc/nsswitch.conf
# Since we want to do NFS we need to start portmap and nfslocking (in
# case it is needed), but portmapper needs loopback starting up first!
#
/usr/bin/ifconfig lo 127.0.0.1 up
#
chroot $NR /etc/rc.d/init.d/portmap start
chroot $NR /etc/rc.d/init.d/nfslock start
# Name lookups etc should be ok by now
chroot $NR mount -o ro,nolock $SERV $CFDIR
... code to run the scripts in the chroot environment ...
chroot $NR /etc/rc.d/init.d/nfslock stop
chroot $NR /etc/rc.d/init.d/portmap stop
cd /
chroot $NR umount $CFDIR
