anyone using the suckless 'utmp'? i'm having difficulties figuring out how to use it...

What would you use it for? Which distro are you currently running?

Well I am running solus right now, but I am trying to get st to open /usr/bin/rc as the shell without changing any variables, so I thought I might be able to use utmp to make st's default shell /usr/bin/rc instead of my user's default shell of /bin/bash.
