The LPRng-3.6.22-3 RPM lists a dependency on the non-existent directory /etc/init.d instead of /etc/rc.d/init.d. The /etc/rc.d/init.d/lpd script attempts to include /etc/init.d/functions instead of /etc/rc.d/init.d/functions.
We are in the process of changing over to the FHS style system. /etc/init.d is the correct location for this. Closing as a non-bug.
Oops, my fault. This IS a bug, fixing it up. We are NOT changing over (yet?), just providing the additonal links.
Got a fix in, versions >= LPRng-3.6.22-7.src.rpm are correct now.
