oh boy oh boy oh boy.
I just read on mandrake.cooker.cvs that kexec kernel module/patch is included in kernel-2.6.6.3.mdk!!! I’ve wanted to play with kexec for months, since I heard about it.
What is kexec you may ask!?! It is totally awesome!!! Especially on shite slow to boot servers like 1/2 the dells with HW RAID controllers in the machine room at work.
kexec turns the machine over to another program. That is, the running linux kernel, turns ENTIRE control of the machine over to another program, such a a boot loader like lilo or grub. This means you can reboot without having to reboot. That is, reboot the OS, without rebooting the system. On machines where POST takes a long time, or Dell PowerEdge 2650’s with PERC and RMC, the PERC and RMC take nearly 60 seconds a peice, and standing in front of a server in a rack in a cold server room is not my idea of fun. I like the comfort of my tiny 6′ by 6′ cube.
So I’ll have to wait a day or two for the rpm to spread to mirrors, but I’m looking forward to using this feature.
