Hi,
my mdev-without-devtmpfs highlighted a couple errors that are not strictly
related to that work. And since that work might or not have a v2, and is
not very likely to be merged at all, let's have the two small fixes rolling
on their own.
Enjoy!

Several inittab steps are redirected to /dev/null. This means any error or
warning printed by these crucial commands would be hidden from the user.
There is no evident reason to hide this output, so stop doing that.

/dev/shm is needed for systems using shared memory. On init-based systems
this directory is usually created in the inittab along with /dev/pts, by
the lines:
package/busybox/inittab:
::sysinit:/bin/mkdir -p /dev/pts
::sysinit:/bin/mkdir -p /dev/shm
package/sysvinit/inittab:
si2::sysinit:/bin/mkdir -p /dev/pts
si3::sysinit:/bin/mkdir -p /dev/shm
However this is broken when static /dev management is selected and the root
filesystem is read-only, showing during boot the error:
mkdir: can't create directory '/dev/shm': Read-only file system
Fix by creating the empth /dev/shm directory, just like /dev/pts.
