Also I think the right solution is to simply call syslinux_hddimg_populate() from the directdisk class vs having copied code for the install of the syslinux specific files (that is how 1/2 the problem occurred in the first place).

Yes it would be nice to have the possibility to enable menu, it can even
be enabled by default once it's working properly and there is an option
to disable it.
