Today, I bought a copy of Solaris Internals: Solaris 10 and OpenSolaris Kernel Architecture by Richard McDougall and Jim Mauro. The previous edition of the book is available in Low Priced Indian Edition (Rs 500) and this International edition costed me Rs 4000 approximately. This book is worth that price.
A quick glance thru the table of contents tells me that there are new chapters added for Process Rights Management, Zones etc.
May take a few weeks before I dig deeper into this book.
