--- Comment #2 from Kubilay Kocak <koobs@FreeBSD.org> ---
Still reproduces  14.0-CURRENT #14 main-n245176-8742817ba62

[koobs@140-CURRENT-amd64-564d:/usr/home/koobs] sysctl -aN | grep jail |grep -E
'.*\.$'
security.jail.param.sysvshm.
security.jail.param.sysvsem.
security.jail.param.sysvmsg.
security.jail.param.allow.mount.
security.jail.param.ip6.
security.jail.param.ip4.
security.jail.param.host.

They "appear" to be duplicates, most with identical descriptions, except
"security.jail.param.allow.mount":
