sysctl kern.msgbuffer capset not implemented with linux-compat jsvc

I have been working on getting a debian install running in a Jail, for which to migrate a physical installation of debian 7 with some NVR software by ubiquiti. I feel like I have a functional Jail but may be running into a limitation of the linux compatibility layer in Freebsd 10.3.

What I'm getting that is rather confusing is the following in the sysctl kern.msgbuffer:

linux: pid 59658 (jsvc): capset effective=0x4c4, permitted=0x4c4, inheritable=0x4c4 is not implemented.

Just looking for some pointers on what might be generating this error... is this the linux compatibility kernel module and how do I determine what 'is not implemented' that would be implemented in a full blown linux kernel to possibly go about submitting a bug to resolve the issue... I have done quite a bit of googling to no avail.

If you would like a more in depth view of the steps I've gone through... see the following:

I have a theory it has something to do with the requirement to comment out echo 0x10 > /proc/self/coredump_filter as linprocfs is not writable and coredump_filter doesn't appear to exist in /proc/self.

Any assistance or guidance would be appreciated...
In reading through my own setup, I noticed a few lines that allowed debugging and verbose output to be returned when starting the unifi-video service... I don't know if the following provides any additional perspective, but I figured I would include it as well...

.... removed a bunch of other startup output...

noticed the set_caps(CAPS) failed for user 'unifi-video'... which seems to coincide with the error seen on the krn.msgbuffer....

After digging around, I found libcap which is referenced in the jsvc start up logs is actually a user space API for elevating a processes individual needs without superuser (root) access like listening on a port less than 1024 on a socket. It seems like this is linux specific as I cant seem to find anything in the freebsd man paged for it.

So I've been reading quite a bit about JSVC and it's inability to modify setcap on Linux boxes. I'm assuming this might be a limitation in the Linux abstraction layer for freebsd as well. Although if this is done differently on bsd hosts it may just not be capable of performing such actions.. I noted on the following link there is information regarding how to enable features within the Linux kernel. So I think I'm gonna try and look at re compiling a custom linux-compat Patch.

in the interim I have just allowed the service to run as root within the jail. :(
Any progress on this?

I'm in your situation where I'd like to run that very same software on FreeBSD 11.

Was set_caps the only problem? Did the NVR run correctly if given root access?
ATM I'm running it under a bhyve visualization (ubuntu 16.04LTS), .. why not use bhyve instead?
