The main reason I didn't consider a jail.d approach is just that I haven't - such things are a little off the radar for me. It seemed very natural to use a configuration file format that other programs already use (e.g. named, apmd, devd). I suppose it's true that the "foo.d" approach is also in use by other programs, though I mostly seem to see those on Linux. And if I did opt for a directory approach, the files within the directory would still need a format - you can't get away from the fact that a config file needs a format. It would be nice to have a general parser for C-style config files, and I looked for such a library when I started on this. But such a library doesn't seem to exist.Perhaps it's time to make one. - Jamie On 04/27/12 22:14, Dirk Engling wrote: > On 26.04.12 22:07, Jamie Gritton wrote: > >> I've finally put my jail(8) changes into HEAD.
