Virtual Kernel in DragonFly

Following DragonFly BSD Digest, I noticed there are some work on so called ‘VKernel’, which is similar to User Mode Linux. It looks interesting.

gpt partition is not visible at boot

December 27th, 2006 by rafan

On a RELENG_6 system, it seems that gpt partition is invisible until a ‘gpt show’ command is issued. So, currently, I have to put ‘gpt show da0′ in rc.early (yes, that’s dirty).

After checking geom_gpt.c, it seems that its start function does nothing on RELENG_6. But, in -CURRENT, it does something. So, my guess is on -CURRENT it is fine. Need to ask some experts.

PXE installation is not hard

December 23rd, 2006 by rafan

Recently, I bought a ThinkPad X60 with Intel Core 2 Duo CPU. Though, I have an external USB CD-Rom, I decided to try PXE installation. I know this long time ago, but never try it out.

In short, you need a DHCP+NFS+tftp server to start. All the tricks are documented here. If you have NAT running on the server, disable it. Otherwise, some funny things happen. PXE installation is not that hard as I thought. Speaking of PXE, I think there is a project about PXE bundle installer. Hope we can see it soon :D
