Hello Pete,
not entirely sure how EPICS initializes dhcpcd. But I would expect that
your application creates a /dev/dhcpcd.conf somewhere. You can add the
"quiet" option to that file:
https://www.freebsd.org/cgi/man.cgi?query=dhcpcd.conf&apropos=0&sektion=0&manpath=FreeBSD+13.0-RELEASE+and+Ports&arch=default&format=html
(Note: The man page is a bit newer than our dhcpcd. But the quiet should
be the same.)
Alternatively there should be a call to rtems_dhcpcd_start() somewhere
(maybe hidden in another call). That function allows an
rtems_dhcpcd_config structure pointer as an argument. That structure has
an argc and argv. Without testing: I think you could pass a "-q" or a
"--quiet" in these to silence dhcpcd. Note that the first field in argv
has to be the program name. So you would have to use something like
const char *argv[] = {"dhcpcd", "-q", NULL};
int argc = RTEMS_BSD_ARGC(argv);
Best regards
Christian

FYI,

Hello Pete,
in modules/libcom/RTEMS/posix/rtems_init.c in
line 1008 (before sc = rtems_bsd_initialize();) there is a / should be a
line with
rtems_bsd_set_vprintf_handler(rtems_bsd_vprintf_handler_mute);
That should suppress all output from the network intitialization?

My application uses dhcp, and the system issues a screenfull of messages every
time the lease is renewed. Is there a way to stop that?
