[PATCH] FC4 cannot load driver disk image on a disk partition

[Akinobu Mita]

Hello,

I tried to load driver disk image on a partition in USB storage device.
(/dev/sda1:dd.img) But It failed.

Steps to Reproduce:
1. create driver disk image (dd.img)
2. put dd.img on USB storage device partition (/dev/sda1)
3. start FC4 installer with "linux dd"
4. select driver disk source as /dev/sda1 and choose the file "dd.img"

Actual results:

anaconda went wrong stage.
  anaconda displays:

---| Insert Driver Disk |---
  Insert your driver disk into /dev/sda and press "OK" to continue.

Expected results:

Successfully load from driver disk image.

I think below patch fixes this problem. but it is untested.

I've not found really good documentation on driver disks.  To create 
dd.img do you just create a normall driver disk and `cat /dev/fd0 > 
dd.img`?

I've been using FC3.  From the source in driverdisk.c it looks like it 
loop back mounts the image and when I try that it seems to find the files, 
but my installer segfaults.

The driver disk works when you use a floppy.

thanks,
dan

Loading driver disk image on a disk partition is not documented.
But anaconda seems to have the code to do that.
This is why I tried that.

Anyway, If we want to load driver disk, we can create driver disk
(not driver disk *image* on a disk partition) as you mentioned.
And we can load driver disk image over NFS, FTP, and HTTP.
So the problem I reported is minor thing.

dd=http://path/to/dd.img
dd=ftp://path/to/dd.img
dd=nfs:host:/dd.img

[PATCH] load driver disk from initrd

[Dan Carpenter]

Anaconda actually has code for using driver disk images from the initrd 
but it doesn't work because of a bug.  The attached patch fixes that.  
There were some variables that weren't getting initialized early enough.

Take a normal driver disk floppy:
zcat ../initrd.img | cpio -idmv
dd if=/dev/fd0 of=dd.img
find | cpio -oc | gzip -9 > ../initrd.img

You can use this to for loading over the network etc.

Looks good to me.  Applied to CVS.
