nixos seems to deviate a lot from other Linux distros. I could not get PKG_CONFIG_MODULES to work. After installing sispmctl is not in the path. Please, provide a description: Which packages are needed? How to build? How to install? How to setup the service?
Thank you for reporting the issue that you faced and suggesting a fix. Neither on Ubuntu nor on Debian I am able to reproduce your problem. I would not know where sispmctl would be sending messages via a socket to the kernel (AF_NETLINK) or locally via socket (AF_UNIX) to another process. Could you, please, describe which operating system and which architecture you are using. Best regards Heinrich
