question about zones

hello, I just got into zones and I have few questions:
is there any way to create zone with some additional customizations?
here is what I did:
# zonecfg -z titan1
titan1: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:titan1> create
zonecfg:titan1> set zonepath=/zones/titan1
zonecfg:titan1> set autoboot=true
zonecfg:titan1> add net
zonecfg:titan1:net> set address=192.168.1.82
zonecfg:titan1:net> set physical=bge0
zonecfg:titan1:net> end
zonecfg:titan1> info
zonecfg:titan1> verify
zonecfg:titan1> commit
zonecfg:titan1> exit
Ok, so that created my zone. Now I have to login and changethe following:
passwd file to point to new root home directory: /root/
add users.
change syslog.conf settings
make appriopriate changes in /etc/hosts file.
make changes to /etc/mail/sendmail.cf
is there any way to automate it? I did create only 10 zones and its not to crazy
to login to each of them and do all those different config changes etc, but I
was wondering if there was any easier way of doing all of them at the creation
time by scripts. I did setup scripts to do most of the stuff with zone creation,
to allocate resources per zones, and to zreate zfs for each zone with all the
settings that I needed but I was wondering if I can automate it even more.
Thanks for any help or pointers that you could give to me...
Chris

Cloning in 11/06 and NV copies over a lot of things, including SMF repository, from what I
experienced. Your /etc/inet/hosts file will probably still be unique and need to be customized after
install/clone, and possibly before first boot. I have a script that does a lot of the sysidcfg
stuff, in addition to the sysidcfg file.
# cat zoneXcreate.sh
#!/bin/sh
. ./zoneXlocal.include
while [ $I -le $M ]
do
echo "$I \c"
HOST=`expr ${HOSTBASE} + ${I}`
# Configure the zone
sed -e "s%X%${HOST}%g" zoneX${ZONETYPE}.cfg | \
sed -e "s%ZONEPATH%${ZONEROOT}%g" > /tmp/zone${HOST}
zonecfg -z zone${HOST} -f /tmp/zone${HOST}
rm /tmp/zone${HOST}
# Install the zone from a master, if it exists
S=`zoneadm -z ${ZONEMASTER} list > /dev/null 2>&1`
if [ $? -eq 0 ]
then
zoneadm -z zone${HOST} clone ${ZONEMASTER}
else
zoneadm -z zone${HOST} install
fi
# Set configuration information prior to initial boot
sed -e "s/X/${HOST}/g" zoneX.sysidcfg > $ZONEROOT/zone${HOST}/root/etc/sysidcfg
echo "${NETBASE}.${HOST}/${NETMASKSIZE}" > \
${ZONEROOT}/zone${HOST}/root/etc/hostname.vnic${HOST}
echo "\n${NETBASE}.${HOST} zone${HOST}" >> ${ZONEROOT}/zone${HOST}/root/etc/hosts
echo "\n${NETBASE}.0 ${NETMASK}" >> ${ZONEROOT}/zone${HOST}/root/etc/netmasks
echo "$DEFROUTER" >> ${ZONEROOT}/zone${HOST}/root/etc/defaultrouter
echo "zone${HOST}" >> ${ZONEROOT}/zone${HOST}/root/etc/nodename
zoneadm -z zone${HOST} boot
I=`expr $I + 1`
done
echo
# cat zoneXlocal.include
### To be customized per host
M=4 ; I=1
NETBASE="10.1.14"
NETMASK="255.255.255.192"
NETMASKSIZE=26
HOSTBASE=150
INTERFACE=e1000g2
MAC="0:3:ba:d8:50"
DEFROUTER="10.1.14.129"
ZONEROOT=/export/zones
ZONEMASTER=zoneX
ZONETYPE=exclusive
#ZONETYPE=shared

Because the global zone has access to the files under <zonepath>, a script can
be run in the global zone which manipulates files "in" the non-global zone.
For example, titan1 has a file called /etc/inet/hosts. The same file can be
accessed from the global zone with a different name:
/zones/titan1/root/etc/inet/hosts.
One precaution: after a zone has been booted for the first time, do not trust
the contents of its files. A sufficiently-privileged user of a non-global
zone may, accidentally or deceptively, modify a file in the non-global zone.
