Happy nameday, FreeBSD!
FreeBSD is approaching 20 years! I guess it all depends on what you regard as FreeBSD’s true birth. The baptism, the first commit to the CVS repository, the first release, or something else? The first commit to the CVS repository was done on “Sat Jun 12 14:49:13 1993 UTC”. That’s 20 years and 6 days […]Read More → Happy nameday, FreeBSD!

The system was installed using UFS for the root filesystem, and the system was […]Read More → ZFS on NetBSD/amd64 6.0.1
CARP on FreeBSD 10.0-CURRENT
I’ve been experimenting with carp(4) on FreeBSD/i386 10.0-CURRENT and FreeBSD/amd64 10.0-CURRENT for the past year or so. carp(4) is no longer a pseudo-interface, but rather accessible on every conceivable interface.Read More → CARP on FreeBSD 10.0-CURRENT
