I imagine you could reduce the startup time on solaris some by
cleaning up the startup script.
Someone that understands ksh should look at this script.
Use of full paths like /usr/bin/ are not recommended for some
builtin commands as I understand it, and overall minimizing the
actual "exec's" this shell script makes would benefit your startup
time on solaris.

This has been noticed by more than one person in Solaris land, just thought
I would pass it on...
