[syslinux] [PATCH] 4 Patches for initrd+= and initrdfile= Options

[Gert Hulselmans]

It could be useful that instead of only being able to specify the file
and the path in the initramfs:

  initrdfile=foo@/goes/to/foo

that the initrdfle parameter can also load a text file with:

  initrdfile=<files_to_add_to_initramfs.txt

where the "files_to_add_to_initramfs.txt" file contains entries like:

foo1@/goes/to/foo1
foo2@/goes/to/foo2
foo3@/goes/to/foo3
foo4@/goes/to/foo4

I don't know what the length of the command line is that can be passed
to linux.c32,
but if it is limitted to 4 kiB, like the linux kernel command line, an
approach like this
might be needed when you want to add a rather large list of files to
an initramfs.
