Hi
I'm trying to setup interface using ifup tool.
"up" section of config file contains the only one line:
program "ifup -v %%=imec" wait;
This command is failed to run from vtund but runs
successfully when started manually with appropriate
substitution.
The output from failed ifup looks like this:
Configuring interface tun112=imec (inet)
run-parts --verbose /etc/network/if-pre-up.d
run-parts: executing /etc/network/if-pre-up.d/bridge

Failed to bring up imec.
I think this problem could be related to ignored and inherited SIGCHLD.
The patch is in the attachment. It works for me.
