Adding User License Agreement in Solaris package

I have asked similar question for Linux RPM (Adding License Agreement in RPM package). Now i have same query for开发者_如何学编程 Solaris package. I could not get any helpful link / details if it is possible. But I have found a package which does exactly the same thing but how it has been implemented, its not mentioned.

$pkgadd -d . SUNWsamfsr SUNWsamfsu

Processing package instance from 

Sun SAM and Sun SAM-QFS software Solaris 10 (root)(i386) 4.6.5,REV=5.10.2007.03.12

Sun SAMFS - Storage & Archiving Management File System

----------------------------------------------------- 

In order to install SUNWsamfsr, you must accept the terms of
the Sun License Agreement.
Enter "y" if you do, "n" if you don't, or "v" to view agreement. y

-The administrator commands will be executable by root only (group bin).

If this is the desired value, enter "y". If you want to change 
the specified value enter "c". y   
...   
...

Any ideas how to implement such thing for Solaris package?

I have found a way to solve it.

The self-extracting binary is the way to do it.

Create a shell script which will first dipslay the end user license and take user input whether user agrees or not.

Once user agrees, extract the binary (solaris package file) embed in the shell script and install it.

To embed installer pacakge, first add a marker lets say PKG_DATA:

shell script contents
exit 0   
PKG_DATA   

Append the package file:
cat pkg_file_name >> your_shell_script

Extract the package and install it:

ARCHIVE=awk '/^__PKG_DATA__/ {print NR + 1; exit 0; }' $0   
outname=install.$$   
tail -n+$ARCHIVE $0 > $outname   

echo "Extracting..."   
pkgadd -d $outname   
rm -f $outname #we dont need it anymore   

exit 0   

PKG_DATA   
<pkg file data here>   

I would implement that using the checkinstall script.

"exit 3" in that script gracefully ends the package installation.

That's not trivial as you need to create a request script and reference it in the checkinstall one.
