As mentioned in the other email, this will force everyone to use /arch/
as the archiso folder. When putting this on USB, you might want to use a
different path - this would force you to edit tons of config files.

I am more and more convinced we should do this for PXE

1) Use a separate configuration for pxelinux, specify /arch as option
210 and "boot/syslinux/pxelinux.cfg" as 209.
2) Use a loadconfig trick, including a chdir (as for isolinux) to switch
directory. I guess ".." in addresses works the same as with syslinux then.

Absolute paths are very ugly. Uglier than a stupid loadconfig trick.
Even uglier than providing two completely different sets of config files
(one for PXE, one for the rest).

On another note: Don't you have to modify the config files for PXE
anyway? You need to add the nbd/curl/nfs options to the command line, right?
