Things look quiet here. But I've been doing a lot of blogging at
dan.langille.org because I prefer WordPress now.
Not all my posts there are FreeBSD related.
I am in the midst of migrating The FreeBSD Diary over to WordPress
(and you can read about that here).

new FreeBSD Diary website.
If you want to add a swapfile, perhaps you should read swap files
first. This article deals with adding a additional swapfile after adding your first
swapfile. So if you already have a swap file (and I'm not talking about a swap
partition), and you want to add another, then this is the article for you.
Out of swap space again
I need yet more swap. So I went and created a new swap file:
# dd if=/dev/zero of=/usr2/swapfile bs=15m count=20
10+0 records in
20+0 records out
314572800 bytes transferred in 40.594 secs (387462 bytes/sec)
Note that the above should have give you a 300Mb file (bs=15m, count=20 or 15Mx20 =
300Mb). Enjoy.
Creating a new device
Before we can use this swapfile, we need to create a new vnconfig
device. Here's how I did that:
# cd /dev
# ./MAKEDEV vn1
Telling vnconfig about the new swapfile
Before I started this article, my /etc/vntab contained this:
/dev/vn0c /usr4/swapfile swap
After adding the new device, here's what the config file looked like:
