ok, it seems only poudriere-devel correctly implements "-i",
and leaves the jail running after "poudriere testport -i ...".

Anyway, I guess I'm asking for help with jails.

On the host I get:

# poudriere ports -l
PORTSTREE            METHOD     PATH
default              svn+https  /pdr/ports/default
# poudriere jails -l
JAILNAME             VERSION              ARCH    METHOD  PATH
ia64                 11.0-CURRENT         ia64    svn+https /pdr/jails/ia64
# df ports    
Filesystem         1K-blocks   Used     Avail Capacity  Mounted on
/pdr/ports/default 138074817 890565 137184251     1%    /pdr/data/build/ia64-default/ref/usr/ports
# 

i.e. the poudriere ports tree is mounted
under the ia64-default reference jail
as /usr/ports. However, for some reason,
this mount happens read-only. So I can
have write access to the ports tree directly
via /pdr/ports/default:

# touch /pdr/ports/default/zzz
#

but not via the jail route:

# rm /pdr/data/build/ia64-default/ref/usr/ports/zzz
override rw-r--r--  root/wheel uarch for /pdr/data/build/ia64-default/ref/usr/ports/zzz? y
rm: /pdr/data/build/ia64-default/ref/usr/ports/zzz: Read-only file system
# 

Is this something to do with various "allow.mount.no***" below?

# jls
   JID  IP Address      Hostname                      Path
    34  -               ia64-default                  /pdr/data/build/ia64-default/ref
# jls -n

#

Am I on the right track at least?

Many thanks
