There's a convention that syslinux configuration snippets
carrying the names of subprofiles involved are picked up
automatically; there were a few special cases already
when this is actually inconvenient, and there's another
one at hand so let's just step up and do it.
NB: this is a sort of a hacky hook though, wish an elegant
interface would come to mind some day.
