We are using print services on our NFS Linux box here. Its running
Redhat 7.3 with the latest updates. There is a custom compiled kernel
using devfs (for EVMS). Below is the error from the status file of the
print queue(s). All the print queues are doing the same exact thing. 

Error:

IF filter 'mf_wrapper' filter msg -
'/usr/share/printconf/util/mf_wrapper: /dev/stdin: No such device or
address' at 2002-12-27-11:36:20.068 ## A=root@pyrodex+192 number=192
process=30771

Also here is my devfsd config file...

Now anyone have any suggestions? If I disable devfs (breaking EVMS) it
works fine.
