Hmmm... That doesn't work for me... The calling script patiently waits for the
called process to finish... Even if I completely wrapper it, e.g.

In the script do:

exec( "/usr/local/bin/reconf-wrapper" );

And 'reconf-wrapper' is:

"
#!/bin/sh

/usr/local/bin/reconf system.dat >/dev/null 2>&1 &
exit
"

Again, the polite PHP script waits until the processes spawned by the wrapper
has finished... If I run the wrapper from the shell it launches the process in
background, and returns immediatly... If I do it from PHP it launches the
process in background, then hangs around waiting for it to finish... :(

I can see probably why it behaves like this, I just don't want it to! <G>
