Hi, perhaps this is a little off topic, but I thought that
LaunchAgents
was introduced in Tiger and was working ok? It seems ok when I test
it,
but this is on a 10.4.11 machine. Do you have these problems only on
earlier versions of Tiger, or is it Tiger in general?
In Tiger there is only one launchd instance, so LaunchAgents are not
loaded correctly because they are launched by the root launchd
instance. This causes all kinds of problems, especially when you
logout, or somebody logs in via SSH. In Leopard and later, there are
multiple launchd instances, one for each user logged into the machine
and attached to the graphics console, so launchd can load
LaunchAgents into the appropriate user bootstrap namespace.
This excellent technote explains is it all:
