The NUC daemon, nucd, runs as a background process to (among other things) automatically mount NetWare volumes as they are requested and unmount them after a timeout period. The volumes are mounted as NUC file systems.
nucd is run automatically from the /etc/rc2.d/S27nuc start-up script. Error conditions detected during start-up are reported in the /tmp/nuc.start file. This daemon must be running in order for the NUC to function.
