[erlang-questions] Stand alone erlang deployment
Thu Nov 12 20:08:37 CET 2009
Thanks for all the great info from everybody. I'm happy to announce that Erlang is the number one contender now, since the current perl libraries for distributed computing are not giving the expected performance.
The issue now is security, with reltool everything works fine, but even on a simple hello world, the reltool deployment allows me to run from the erlang shell something like: os:cmd("whatever!!").
Is there a way to inhibit this behaviour?

Besides the icon stuff, you can do this with Reltool.

When you generate a target system with Reltool it will by default not
need any installation script to be run. You can just copy the files to
the new location and start the VM.
If someone by some obscure reason wants to have the old behavior
(with a mandatory installation script) it can still be achieved by setting
the Reltool parameter relocatable to false when the target system is
