I've been using and deploying FreeBSD since it was 386BSD 0.1 back in 1994. This page collects pointers to some recent stuff I've done with FreeBSD.

FreeBSD jails are great. Here are a bunch of my blog entries on jails:

• Setting up a thin jail.
• Setting up a thin jail for Squeak Smalltalk.
• Reconnecting to a Lisp running in a remote FreeBSD jail with SLIME via SSH.
• Managing jails.

• Upgrading XFree86.

• SQLite Threading FreeBSD CMUCL Oh My!
• Building CMUCL
• CMUCL FreeBSD -lc_r
• SBCL FreeBSD -lc_r
• Use Gnu Pth?

One of my current interests is in getting CrossOver Office 3.0 for Linux to work on FreeBSD, because I picked up a copy that was on special offer. ;-) When I try out the stuff here, I'll blog about it.

Marcel Moolenaar tells how to add missing Linux system calls:

In the linux kernel source tree, look in arch/i386/kernel/entry.S.
There you'll find all the syscall entry points. Currently they go
all the way to 271. Also look at arch/alpha/kernel/entry.S...

Then, in /sys/i386/linux look in syscalls.master.  There you'll
see we only have syscalls up to 221. See also /sys/alpha/linux...

One could:
o  Add proper prototypes to syscalls.master of the 50 new syscalls
   we don't know about,
o  Declare all these syscalls as dummies (see linux_dummy.c) to begin
   with,
o  Really implement those syscalls that are used in practice.
