Fix udev SysV init script and d-i start script to not write to
/sys/kernel/uevent_helper unconditionally to not fail on a kernel with
CONFIG_UEVENT_HELPER unset.
Closes: #756312
"kmod static-nodes" will write its output to /dev/stdout by default.
That device node is created by udevd as a symlink to /proc/self/fd/1.
Since we run make_static_nodes() in the udev SysV init script before
udevd is started, this device node is not guaranteed to exist and kmod
fails to deal with that properly.
As a workaround, use "kmod static-nodes --output=/proc/self/fd/1".
Closes: #757830
Drop the obsolete check for /sys/kernel/uevent_helper from postinst and
the SysV init script and do not unconditionally overwrite it in the
initramfs hook. Since a long time now udev has been using the netlink
interface to communicate with the kernel and with Linux 3.16 it is
possible to disable CONFIG_UEVENT_HELPER completely.
Closes: #752742
This file created /dev/root, but programs should not rely on that
anyway. If this breaks anything, we need to fix it in that particular
program.
