Today, I ordered a physical print proof of FreeBSD Mastery: Specialty Filesystems.
The ebook is now available on my site, and is infiltrating other bookstores as you read this. Each ebookstore has its own internal speed–while I uploaded to Amazon first, I expect it to make the books available last.
I’ll keep the book page updated when FM:SF hits various stores.
Print should be available next week, barring problems.
