/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 it by creating the empty /dev/shm directory, just like /dev/pts.
