template www/poudriere-nginx : mount_nullfs mount points are empty

[s1dh]

Once I create a 12.2-RELEASE jail (thick or not) , I apply the template on it.
The mount command from the host is showing the corresponding the nullfs mount points.

I already have packages built on my poudriere host, and once I enter the jail I can see no packages in the packages directory
From the host , the mount points are present, and I can cd in them
If I add a file from the host on the source , I can see it on the jail mount point destination.

Shoudn't the CP usr provided in the template copy the whole existing packages already present on poudriere host (among other things ) ?
Or else it would means that this jail/template should be running BEFORE building any packages with poudriere, in order to be able to see tne built packages in nginx directories, and that doesn't make sense for me.

Thanks for any tracks or tips you could provide on this issue.

OK regarding this it seems to be a known problem but ignored . It would be great to add an entry in the doc for those using template with ZFS based systems (thx @cedwards g for pointing that out ! )
