Yes, that is correct. There should be a file /run/sysconfig/ganesha and that will have the currently used one. There are some plans to dump the config values using dbus, this way you get exact run time values.

There is one code path (accessing symlinks) where we are not decrementing the open_fd_count. This may explain why the actual open count is less! Usually, open_fd_count should be less than the actual count from /proc as the open_fd_count doesn't count sockets and some other opens. Thank you Bill, we will fix the symlink case as well.

Note that strictly speaking, the values in /etc/sysconfig are in general the
values that will be used at next restart - it's totally possible for the system
to boot, the then-current values be picked up from /etc/sysconfig, and then any
number of things, from configuration automation tools like Ansible, to a
cow-orker sysadmin armed with nothing but /usr/bin/vi, to have changed the
values without you knowing about it and the daemons not be restarted yet...
(Let's just say that in 4 decades of doing this stuff, I've been surprised by that
sort of thing a few times. :)
