After managing to get a Fedora ISO to rebuild successfully (for a USB stick) after adding a kickstart file (http://serverfault.com/questions/548405/), I now have an issue with locating the kickstart file on the USB media.

When this is done from a CDROM you can simply kickckstart by adding this parameter to boot:

linux ks=cdrom

This will kickstart (providing the kickstart file is named ks.cfg and is in the root of the disk).

Now, obviously this will be different for the USB drive, so from my research, I assumed that this line would do the job:

linux ks=hd:sdb1:/ks.cfg

Evidently this does not work. I get an error informing me this drive is already mounted and cannot be remounted.

EDIT: Actual error message:

mount: /dev/sdb1 is already mounted or /run/install/tmpmnt0 busy
Warning: Can't get kickstart from /dev/sdb1:/ks.cfg

To test that the syntax was correct I placed the kickstart file on another USB stick and loaded the same command to grab ks.cfg from the new location:

linux ks=hd:sdc1:/ks.cfg

This does work (providing USB sticks are mounted in order, boot -> sdb1, kickstart -> sdc1). The install will kickstart and complete the install with no issue. Obviously having to use 2 pen drives is somewhat frustrating and unreliable.

Is there a way around this?
