initramfs-framework: fix boothang when console=null
If console=null systemd-udevd throws an assertion which prevents the system from booting. This patch redirects stdin, stdout and stderr to /dev/null in case that the console can't be opened so that udevd still boots. A systemd issue was reported here. However, they will not fix this specific use-case: https://github.com/systemd/systemd/issues/13332 (From OE-Core rev: dd6ee0b06cd8df6204cf600050516d15172302ea) Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
