Re: Converting system to raid

["Timothy D. Lenz" <tlenz@vorgon.com>]

Yes, the default setup. But that is because the supplied kernel builds raid as modules. I build a new kernel with stuff needed for
my system ecept for dvb stuf which I get by building v4l tree to get newest drivers. And I build raid into the kernel. Since I
havn't needed ramdisk for anything up till now and you are not suposed to need it when raid is built it, ramdisk is not compiled in
or as a module.

Looking into "I have 2 computers that I am trying to convert to raid.
Both where setup with debian netinst cd to hda" - debian has initrd
support within their kernels.
