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.

Random suggestion : adding a one-line comment before these two entries describing what they are for (i.e. sumup of the above) :)

I wanted to remove them because I was cleaning my fstab of old entries that I dont use anymore, so I found those two in the middle of the way, I guess they will have to stay there On Fri, Mar 26, 2010 at 1:22 AM, Thomas Bächler wrote:

Patches welcome.

Personally, I don't think it's worth the time - anyone who is going to mess with these entries is either expected to know what they are for or fail miserably. However, as someone who has been messing with this stuff for 10 years, I am probably not the right person to ask.
