map iso image to /dev/cdrom
 
Hi,

I'm installing Fedora and ran out of CD's to burn, so I uploaded an image to a USB drive, did CTRL+F2 and was able to mount the USB and again "loop mount" the iso image. However the installation still say's "insert disk 4". Is it possible to have /dev/cdrom goto the iso image. Or somehow to have the installing use the iso image on the usb.

I'm in the middle of the installation right now.

Thank you

Edit:
Pusing CTRL+F4 or maby it was F5 I was able to see the error messages and the installing was accessing /mnt/source so I mounted the iso image there I got an error message saying "this is not fedora CD" and after a couple of "ok" click. away it went :)

yay, 4 CD's the live CD is only 1CD. It would be great if there was a not "net install" but a installation CD that only requires one CD.

anyway it works :)

You could try producing a symbolic link from /dev/cdrom -> /dev/loop0 assuming that loop0 was used. Link to the loop device and not the file itself.
/sbin/losetup -a
will list all of the loop devices and the iso file so you can tell which loop device to link to.
or "file -s /dev/loop?" will list filesystem information on the first 10 loop devices.
The install program may be using the /dev/sr0 device instead of /dev/cdrom. On mine, /dev/cdrom is a symbolic link to /dev/sr0.

Some installers allow installing from iso images, after booting from a small net install disc. But you are switching install sources in the middle of an installation.
