Per,
You should be able to use `launchctl asuser` for this purpose, eg.
$ launchctl asuser launchctl unload /Path/to/plist
$ launchctl asuser launchctl load /Path/to/plist
On El Capitan, you can use `launchctl bootstrap` and `launchctl bootout`, eg.
$ launchctl bootout user/$uid /path/to/plist
$ launchctl bootstrap user/$uid /path/to/plist
Note that both of these will load your job into the user's background session
and *not* the user's GUI session. This means that your job must have a
LimitLoadToSessionType value of "Background".
If you want to load your agent into the user's GUI session, your approach below
will work just fine, though I'm not sure why you're chroot(2)ing.
On El Capitan, you can modify the above commands to be
$ launchctl bootout gui/$uid /path/to/plist
$ launchctl bootstrap gui/$uid /path/to/plist
if you want to load the job into the user's GUI session, and you won't have to
go through any weird tricks like below.
Before you ask, yes, we know it's a mess. Unfortunately, we're very constrained
by 10+ years of legacy behavior.
