Dear Abyss: the FreeBSD Journal Letters column, years 1-6

Only Footnotes

Special Editions
These are not commercially available anywhere.
FreeBSD Mastery: Advanced ZedFS
Made for Allan Jude. Discusses ZedFS rather than ZFS throughout. Contains an additional footnote that Allan still hasn’t found. (Yes, I know the French is wrong, I should have reached out to my French-speaking readers.) Five copies exist.
FreeBSD Mastery: Jails (Bail Bond Denied Edition)
An edition made for charity auctions, with the cover art I would be forced to use if I was in jail and did not have access to artists. Five copies exist. I have one, one was auctioned at BSDCan, one at the Penguicon charity auction, and one was auctioned for Soroptimist International Grosse Pointe.
Ed Maste
When I released Ed Mastery, I didn’t realize that hundreds of people would think of FreeBSD’s Ed Maste and decide I was writing Ed Mastery. It’s the same as the regular edition, except the ry is struck out everywhere. Five copies exist. I have one, one went to the BSDCan charity auction, and poor Ed got three as a thoroughly inadequate apology.
Ruin Your Mail By Running It Yourself
Run Your Own Mail Server was written with a Star Wars motif, referencing the dominant providers as the Email Empire and casting independent operators as rebels. Run Your Mail By Running It Yourself is the Empire’s release of captured rebel propaganda, with an introduction and additional commentary by Darth Mailer. The only way to get this was to sponsor the book or back the Kickstarter. Sponsors also got an exclusive challenge coin.
