Host OS FreeBSD-14.1
Jail OS FreeBSD-14.1
Samba-4.19

I have an iocage managed 13.2p9 jail that runs samba-4.13. I have upgraded a copy of this jail to 14.1 and installed samba-4.19. When I start samba_server on the upgraded jail I see this:
Code: 
# service samba_server restart
Performing sanity check on Samba configuration: OK
Stopping samba.
Waiting for PIDS: 17350.
Performing sanity check on Samba configuration: OK
/usr/local/etc/rc.d/samba_server: WARNING: samba_server: cannot fdescfs mount to /var/run/samba4/fd
Starting samba.

The setting for this jail are:
Code: 
. . .
enforce_statfs:1
. . .
mount_fdescfs:1

The host system sysctl does not allow setting security.jail.param.allow.mount.fdescfs:
Code: 
 sysctl security.jail.param.allow.mount.fdescfs=1
security.jail.param.allow.mount.fdescfs: 0 -> 0
The samba_server service starts in the upgraded jail. But it gives the warning about fdescfs. What are the implications of samba_server being unable to fdescfs mount?
