Booting

[Bas Wijnen]

Hi,

Currently my system boots until task.  I still haven't tried Marcus' 
deva things.  Anyway, I was wondering what more is needed to boot the 
system.

I would expect that after task, a ramdisk can be used as rootfs, from 
which deva can be started.  I know the idea is to use a working deva for 
starting rootfs, but that would put limits on the deva boot (with a root 
fs, it can consist of normal processes, as they have everything they 
need: physmem, task, and rootfs).  Since a ramdisk wouldn't need any 
device drivers, I don't see a problem with it.

Well, I see one problem: the ramdisk is only used for bootstrapping, and 
should be disposed of when the system is running.  So it would be useful 
to have a "change root fs" method at least for deva and the first device 
drivers (particularly harddisk and the "real" rootfs).

Am I right that "normal" processes can be started when the root fs is 
ready?  Can libc already be compiled?  (I expect every normal process to 
need it.)

Thanks,
Bas
