What is the usecase for this feature?
Is there als a "import"

Works not on my machine:

$ ./activemq export --file=archive.tgz

Ah ok. What are the known usecases?

The activemq init script provides also the functionality to create and
run multiple instances on the same machine.
This mechanism also provides a independent script environment configuration.

The described problem happens because the file "env" has exec
permissions and the activemq bin folder is part of the PATH variable?
The "env" file does not need exec permissions, but this might be a
typical problem.

Probably we should move the "env" script to conf/env (i hate changing
file locations, because creates problems for the users).
We should also rename the script "diag" to "activemq-diag" or we should
add this functionality to the init script.
I think the second possibility might be better - because this also
allows access to the script configuration.

I also want to drop the "activemq-admin" script, because the
functionality of this script is redundant to the "activemq" script.
What do you think?
