If we don't set PATH, then the shell will specify one for us. Busybox adds the sbin dirs, but bash does not. I hit an issue where bash (among other things) ended up in my initrd and the boot scripts failed due to a bad default PATH. While that is a separate issue, we should not be at the mercy of the shell's default PATH. Update the initrdscripts to all specify: PATH=/sbin:/bin:/usr/sbin:/usr/bin (From OE-Core rev: 4617ae0f433876037c2c9a0dfdb5e373e7a5c77b) Signed-off-by: Darren Hart <dvhart@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
