[syslinux] Chainloading / Nested PXELINUX [SOLVED]

[msacks]

I was able to solve the problem with the following configuration:

label custom1
MENU custom1
kernel pxechain.com
append ::custom1/pxelinux.0

label custom2
MENU custom2
kernel pxechain.com
append ::custom2/pxelinux.0

configdir1/pxelinux.cfg/default
configdir2/pxelinux.cfg/default

Then I dropped the custom pxelinux.0 files in their respective
directories, confgdir1 and configdir2.
