The system will be running FreeBSD 8.0-RELEASE-p1. I'm wondering about the use of the COMPAT options in the kernel config. COMPAT_43 COMPAT_43TTY COMPAT_FREEBSD[4-7] I'm not aware of any software I use which requires certain compatibility with old system calls. The system will be running PHP, Nginx, PostgreSQL, InspIRCd, and other small applications (The latest stable releases of each). Is it recommended that I keep certain compatibility flags? If I recall correctly, previous documentation claimed that it was required to keep COMPAT_43TTY, but I no longer see this in the handbook. Thanks for the help.
