FUSE file systems in freebsd 12 jails

[James B. Byrne]

I was finally able to mount a fuse file system as root inside a jail
running on FreeBSd12.0.

My /etc/sysctl.conf on the host system contained:

security.jail.enforce_statfs=1

My 9ez)jail configuration contained:

. . .
param3="enforce_statfs=1 allow.mount=1 allow.mount.devfs=1"
param4="allow.mount.nullfs=1 allow.mount.fdescfs=1"
param5="allow.mount.fusefs=1 devfs_ruleset=4"

export jail_hll_theheart_parameters="$param1 $param2 $param3 $param4
$param5"

However, inside the jail when I display the sysctl variables related
to this I see a lot of deprecated warnings:

security.jail.mount_allowed: Processes in jail can mount/unmount
jail-friendly file systems (deprecated)
security.jail.mount_devfs_allowed: Jail may mount the devfs file
system (deprecated)
security.jail.mount_fdescfs_allowed: Jail may mount the fdescfs file
system (deprecated)

and so on.

Are these related to the change to jail.conf in 9.1 and can therefore
be ignored?
