why bother with porting to linux if the main target is Solaris. It isn't
more difficult to install Solaris on a PC than it is to install Linux.
Just go to http://www.sun.com/software/solaris/get.jsp, download the iso
images, burn them and install it.

Then learn a little bit about the tools on Solaris (dtrace, truss,
apptrace, libumem, ...) and available for Solaris (Sun Studio 10, ...)
and you will find out that porting to Solaris is easiest on Solaris. And
IMHO developing for any generic UNIX target is easiest on Solaris, too.
Linux can't match Solaris concerning portability and compability to
standards - it isn't even compatible to itself (learnt it myself the
hard way)...

And Solaris is FREE, too.
