Just got back to work where I have an smgl box with static dev, and
using urxvt.

- udev/eudev/systemd not installed
- rxvt-unicode version 9.20
- glibc version 2.19
- /dev/ptmx   crw-rw-rw-  root tty
- /dev/pts    drwxr-xr-x  root root
- kernel 3.15.2

And I did find the proper fix, it was not to leave devpts out of fstab,
but that you need to specify some mount options:


   devpts  /dev/pts  devpts  defaults,gid=5,mode=620,ptmxmode=000  0 0


leaving devpts out of fstab is the fix for systemd as in that case
systemd will handle it, while having it in fstab manually with incorrect
mount options will break your system. Not exactly sure about udev/eudev,
but I guess if you set the right mount options in fstab it should work
right.

The kernel option that I was remembering somewhere was not related to
pts but was devtmpfs stuff which completely fscked up my static dev
setup as it threw away my devices every time. So if you would like to
ditch udev/eudev and go static remember to disable devtmpfs in your
kernel config.
