This is definitely NOT SAFE! If you don't have /dev/shm, POSIX shared memory will use the same tmpfs filesystem as /dev, which is currently limited to 10MB - POSIX shared memory blocks might be much larger. As for removing /dev/pts, I was tempted to tell you to do it, as it's SO funny what happens: No pseudo TTYs are available anymore. This will effectively prevent ssh logins, screen, any X terminal and probably many more applications from allocating a TTY, so the only way to get a shell is to login via a real TTY (console). I am curious, why would you want to remove these? I am glad thouh that you asked BEFORE killing your system instead of after.
