            Bug ID: 27316
           Summary: [linux-only] shm_open should not guess or test for
                    /dev/shm existence
           Product: glibc
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: crrodriguez at opensuse dot org
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

Just like the case of /dev/pts that was recently removed, the C library should
not attempt to guess how/what/how /dev/shm is mounted or not. in the rare case
the mount point is not there it should just fail with the error code returned
by open("/dev/shm/name", ....) 

/dev/shm is nowadays always mounted by either the init system, initrd etc.
