I'm only guessing, as I don't know python very well, let alone "Twisted",
and you've given zero information about the process that is spawning
liquidsoap, nor what test.liq is even trying to do - but from what I've
found about that error in liquidsoap, my best guess is one of the
following, in descending order of likelihood:
1. setting env={'HOME':....} means that the spawned process has only the
HOME environment variable, all other normally present environment variables
are not passed on to the liquidsoap process, so it fails trying to access
something it needs to access because it can not find it; or
2. the process is running under a UID without permission to read test.liq,
or maybe write in the /home/edorado/liquidsoap folder
In the case of 1), you'd need to copy *os.environ* and change *HOME* in the
copy, then use this copy in the env= part of spawnProcess
In the case of 2), perhaps you need to set the *uid* (and *gid*) of
spawnProcess to be that of the "edorado" user
