FreeBSD Mastery: Specialty Filesystems is now in copyediting. The ebook should be available by the end of January at all major vendors, and the print in February. The book covers everything from removable media, to FUSE, to NFSv4 ACLs, iSCSI, CIFS, and more. If you act really quickly, you can get the electronic early access version at a 10% discount. You'll get the final ebook when it comes out as well. (This offer evaporates when the final version comes out.)
