[RFC] kexecboot: passing extra cmdline arguments

[RFC] kexecboot: passing extra cmdline arguments

[Andrea Adami]

The new linux-kexecboot package provides a brand new 'second stage bootloader'
thus allowing to boot from different media (SD, nand,...).

The problem I see whit it, is that the kexec'ed kernel looks for cmdline in
/boot/kernel-cmdline, but that cmdline is statically compiled at build time and
ignores the 'mtdparts=' bootarg.

The patch attached to oebug 4520 provides a way to selectively filter
the cmdline of the
first  kernel (coming from bootloader) and pass it to the new kernel.

Comments and corrections are welcome!

Andrea

Hi,

thank you for an interesting addition.

The most important question for me right now is "How do I use this?" 
Unless this will be the default from now on, the best place to document 
the answer to this question will likely be the wiki.
