Make yourself a package

In the world where the Good Security Practices becomes Science Fiction, there was an Admin who wants to train himself in Solaris Packaging.
He has written down the script, which has made his Lord the Legend ;-)
Now, let's put some light on it.

The script takes .ssh folder files from the specified user of template machine, and turns it into .ssh folder of root user on target host. There are also the configuration changes, inside of either /etc/default/login file, or /etc/ssh/sshd_config one.
Do not try this at (production) home!

Core system support - the journey begins

OK, I've installed 'core system support' software group. Solaris has started.
What now? There's for ex. no ssh service, no bash or zsh shell.
So I've decided to mount dvd image and install additional packages.

But... which dsk device is the right one?
No mounted device, no vfstab entry, no cdrom life marks on planet Solaris.

I've found it finally with:

for d in `ls /dev/dsk/*s2`; do prtvtoc $d; sleep 2; done

The right one is that with only one slice, with sector count of 4509440 (dvd image size):

* First Sector Last
* Partition Tag Flags Sector Count Sector Mount Directory
0 5 01 0 4509440 4509439
2 5 01 0 4509440 4509439

Mount:

mount -F hsfs -o ro /dev/dsk/c1t0d0s2 /cdrom

and install desired software:

pkgadd -R /a -d /cdrom/Solaris_10/Product
[...]

Select package(s) you wish to process (or 'all' to process all packages).
(default: all) [?,??,q]: SUNWsshcu,SUNWsshr,SUNWsshu,SUNWsshdr,SUNWsshdu,SUNWbash,SUNWzsh

I've used the -R switch because I've done the work inside the shell session invoked from the Installation menu.
The root system has been mounted at /a directory.
