Stub out `pa_start_child_for_read`.
https://labs.riseup.net/code/issues/12325
As far as I can tell, the main suspect call is pa_start_child_for_read()
in libpulsecore. As far as I can tell:
- The only consumer appears to be the
gconf
module, which is hardcoded to executegconf-helper
. - Despite what the Tails bugs says, this does not appear to directly be exposed to any IPC calls.
Since gconf
doesn't exist inside the sandbox this should be harmless, but I might as well stub it out anyway.
