/proc/cmdline bug

[Ludwig Schwardt]

It seems that /proc/cmdline is broken in kernel 2.4.20. A kernel patch is
available at http://www.ussg.iu.edu/hypermail/linux/kernel/0301.2/0873.html.

The negative effect on FAI is that very long kernel command lines get trashed
in the eval_cmdline routine in subroutines-linux (e.g. when you send static ip=
parameters).

The problem goes away when the expansion $(< /proc/cmdline) is replaced by
$(cat /proc/cmdline) in line 28 of subroutines-linux.
