It occurs to me that we could fix this by adding a feature. If we had something that looked out for some string, and would interpret it as an instruction to immediately chain into a new file, ignoring the rest of the current file, then one could specify the preseed to use in the iPXE config, by adding something like this near the start: # DEBCONF_CHAIN_LOAD(preseed.cfg) If we were looking for /DEBCONF_CHAIN_LOAD([^(]*)/ then it would probably work in anything that has a way of specifying comments, since it could as easily find it after '// ', '<!-- ' or whatever, although we'd need to survive whatever preamble such files might have -- I guess we could additionally scan for that string anywhere in the file before throwing the problematic error. This ought only require us to use the parameter to populate preseed/include and then stop processing the current file.
