OTP Team:

We ran accross the following issue with run_erl:

~>cat /etc/redhat-release
Red Hat Enterprise Linux ES release 4 (Nahant)
~>cat /proc/version
Linux version 2.6.9-5.ELsmp () (gcc 
version 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)) #1 SMP Wed Jan 5 19:30:39 
EST 2005

 >erts-5.4.9/bin/run_erl var/tmp/test var/log/test "ls"
run_erl [17489] Wed Oct 12 14:25:11 2005
Could not open pty master

Apparently this version of Linux doesn't have any /dev/pty devices 
installed:

 >ls -l /dev/p*

Is this an oversight in run_erl, or you could recommend a work-around?

Thanks.
