[syslinux] Config-file-switching code in syslinux-3.40-pre7 worth testing out

[H. Peter Anvin]

Hi all,

Being able to switch between config files has been a long-requested 
feature.  Well, in syslinux-3.40-pre7 I think it's finally implemented 
in a way which can be classified as "working".

If you have a need for this feature I would like your opinions, 
including whether or not the implementation as it stands fits your liking.
