[Yaird-devel] Overriding some probing

Hi,

I am wondering if it would make sense to implement options to yaird
making it possible to override some steps.

I want to produce a complete system in a chroot destined to run on
different hardware (USB flashdisk and different mainboard) than the
current machine.

I imagine yaird supporting --rootdev=/dev/sda and --rootfs=ext3 to
avoid /dev/hda from the host system being ananylzed and used, and
- --modules=uhci,uhci-hcd,ehci-hcd,usb-storage to add and load (in that
order) the modules (and their dependands sd_mod, scsi_mod and usbcore)
required for that device to show up in sysfs when booting.

If possible to "disable" probling like this, then perhaps even the
problem of no upgrade path from a running 2.4-based system could be
solved: A helper tool could use lsmod to produce a bloated but possibly
working ramdisk image from a non-sysfs host.


Does it make any sense?

The reason I say "helper tool" is that I don't expect you to want to
support and maintain such ugly hack as part of yaird - only the
underlying mechanism!
