Again, WORLD_FLAGS and/or KERNEL_FLAGS don't work for you?
Yes, it would be better that whole release procedure works with make
-jN, but most of the time spent is "make buildworld/buildkernel" dur
Thanks guys, for explaining the swap system to me. I have a good
understanding of how the system works now. I want to particularly
thank Matthew Dillon for taking the time to lay down the technical
details as he did. Being able to ask a question like this and get it
answered so well is what put
:Is NSWAP tied to the NSWAPDEV kernel option, or is it the actual number

:actual number of swap devices a useful for improving memory usage? Is
:NSWAPDEV just a compile-time tunable, or is there a sysctl to do the
:same thing?

I never saw any negative block numbers in on-disc stru
Negative block numbers are used by UFS to represent the indirect blocks
associated with a file, while positive block numbers represent the
contents of the file.
These are logical block numbers, which are fragment-sized (1K typically).
So, 2^31 x 1K = 2TB.

Woo-hoo! I finally got a 'make release' to work! Thanks for
everyone's pointers.

Hi all,
I'm trying to get a wireless card going in a desktop machine. The
wireless card is a ORiNOCO Wireless LAN PC Card
The PCI->PCMCIA controller has a texas instruments chip on it and
appears to be made by Elan.
This combo works under XP but does not work under FreeBSD 4.6
The pc card worked
