$XDG_RUNTIME_DIR is not well set on my computer and this causes upstart to write PID files to my home folder. May I know what it should be and where to set it?
As far as I can tell, it is of the form:
/run/user/$(id -u)
For example, my UID is 1000, so XDG_RUNTIME_DIR is /run/user/1000. You can try setting it in ~/.pam_environment:
echo "XDG_RUNTIME_DIR=/run/user/$(id -u)" >> ~/.pam_environment
I couldn't find any sources for this, though.
