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.
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).
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
