Bug#395920: kernel commandline parameters only useful during preseeding are copied into the target

[Philip Hands <phil@hands.com>]

Package: preseed
Version: 1.18
Severity: minor

At present all the kernel command lines (in the syslinux files at least)
end in --, so anything after that is going to get put on the kernel
command line of the target system.

We could search for things that match preseed aliases, and things with /'s
in them, and strip them out automatically. Alternatively, we could
update the documetnation to reflect the fact that by adding another --
on the typed boot prompt, the user can choose which parameters they want
copied (since only those things after the last -- are copied), or we
could do both so that in most cases people would not be required to type
the extra --

Cheers, Phil.
