If I'm reading it right, then yes the behavior on creating jails if intended. The defaults in jail.conf are only defaults to the jails listed in jail.conf, not defaults to command-line-generated jails. So even if you only include an empty block for the jail, it then is a jail.conf jail and not a command-line jail.
For the non-persistent jail poststop scripts, the only way to run them outside the jail is to have a process outside the jail to run them from. Cron isn't a perfect solution, but a pretty workable one. If your jail has a single process that runs from start to finish (i.e. not something like a typical "command=sh /etc/rc"), then you could simply have a subshell that runs the jail and then runs the poststop script itself: # (jail -c name=foo command=sleep 10; echo doing cleanup) & You may be interested in the suggested patch for jail notifications in devctl. That way, a jail-watch process can tell when jails start and stop. - Jamie On Fri, Jul 19, 2019 at 10:29 AM Luca Pizzamiglio <pizza...@freebsd.org> wrote: > Hi all, > > I have 2 silly questions and I think I know the answer. > I'd like to use the command line jail tool start and configure my jails; > however, I'd like to have defaults set up in a central place. > > I thought I could put those defaults in /etc/jail.conf and then dynamically > create my jails with the cli tool. > However, if the jail create (or stop) is not explicitly listed in > jail.conf, the defaults are not applied. > If I add an empty configuration block, then the default values are applied. > > Is this an intended behavior? > > The second question is about not persistent jails. > Once all processes in the jail exits, the jail is automatically destroyed. > However, without invoking jail -r , there is no way (that I'm aware of) to > invoke a poststop script automatically. > Is there a workaround or a suggested way to have a callback/script invoked > when a jail disappear?
