Do you recall why you did "vnconfig ... && swapon ..." instead of using the "swap" option to vnconfig? I think it's probably better to bring /etc/rc in to line with the documentation, rather than the other way around (but continuing to use vn0b instead of vn0c. This would make the line vnconfig -ce /dev/vn0b $swapfile swap in /etc/rc. Thoughts? This is something that can be postponed until after 4.3.

Well blow me, erm, down! I didn't know vnconfig would do the swapon() itself if you used the swap argument. I agree that this should be changed as you say. - Jordan State Changed From-To: open->closed Fixed properly in the FAQ, and in RELENG_4's /etc/rc code. Thanks. |
According to the FAQ, to swap immediately, you invoke: vnconfig -ce /dev/vn0c /usr/swap0 swap But /etc/rc does the following: vnconfig /dev/vn0b $swapfile && swapon /dev/vn0b I'm not sure whether it matters whether you swap on vn0b or vn0c, but it would cause less confusion if the two were consistent. (I checked with jkh, who said: Not sure it always matters, but "vn0b" is certainly more "correct." )
