[LineControl-development] linesrv doesn't close standard file descriptors

[Jonathan R. <jo...@te...>]

I've been using linesrv for a month or two and it has mostly 
worked great; thanks for all the hard work.

I've noticed that linesrv goes into the background on startup, 
but doesn't close its stdin, stdout, and stderr. I think this has 
been causing the linesrv process to hang when it runs a script 
which produces output.

I have attached a patch against linesrv-2.1.18 which removes a 
redundant call to fork and attaches all three standard file 
descriptors to "/dev/null", which seems to be the right thing to 
do, since it is what other daemons do.

This should address a bug report which has been open for more 
than a year:
