DragonFly kernel List (threaded) for 2007-05
Re: HEADS up on HEAD
:I'm a long-time follower of HEAD, but I admit I don't understand the

:If I build world+kernel now, what kind of tasks should I expect to have
:To be specific, I'm running DF from an extended partition (a bit out

Well. I've done my best to test things so hopefully nobody will get
blown up. I did test a simple extended partition so it should be ok.
But, it might be a good idea to do a backup first, just in case. I am
messing with the low level disk partitioning code after all!
Here's what I would do.
* cp /kernel /kernel.bak
* buildkernel blah blah, installkernel blah blah, reboot
It should be able to reboot, the mount device minors don't change,
only the master raw device and the slice devices, so the new kernel
should be able to mount everything up even though the devices in /dev
haven't been upgraded yet.
If it reboots and mounts the hard disks ok, try the rest of the update.
* buildworld, installworld, make upgrade
* I don't think make upgrade will go that deep into the disk devices,
so after you make upgrade you will have to finish adding the devices
manually. Here's a cute trick:
I still have a bunch more to do. Only one major piece left that can
potentially blow things up, but after that the disklabel will be
disconnected enough from the disk management code that I can abstract
it out into a pluggable API and start working on GPT.
