I'm setting up an installer using both PXE and USB, and it works well, however I need to add a few different options to the boot menu to use different preseed files. This is for different situations, like whether or not to set up software raid, and with how many disks, etc.
So ideally, I'd like to roll one initrd image containing several preseed files, and specify which one to use with a kernel argument, as detailed in the manual. However, this isn't working. It seems that no matter how I specify preseed/file= , the installer will only look for /preseed.cfg .
Here is an example of my pxelinux.cfg/default file (a very similar config exists for syslinux as well):
DISPLAY boot.txt DEFAULT install_raid_1disk LABEL install_raid_1disk kernel installer/2b/linux append vga=normal initrd=/installer/2b/initrd.gz preseed/file=/preseed-net-raid-1disk.cfg -- LABEL install_raid_2disks kernel installer/2b/linux append vga=normal initrd=/installer/2b/initrd.gz preseed/file=/preseed-net-raid-2disks.cfg -- LABEL install_noraid kernel installer/2b/linux append vga=normal initrd=/installer/2b/initrd.gz preseed/file=/preseed-net-noraid.cfg -- PROMPT 1 TIMEOUT 20
