As an experienced Solaris and NT administrator, I have been waiting a long time for a book which covered all of the core Solaris material which I learned through experience. This book covers all of the material which makes Solaris distinct from other flavors of UNIX (like HP/UX and Linux). I like the way that the author has given examples of how to get things right (like a whole chapter each on SAMBA and NFS), and how to fix things that go wrong (like filesystem corruption - there are some great examples for using fsck). But I think there should have been more coverage of IPv6 and server clustering.
