calls to "system" prematurely ends chroot_setup.sh

To recreate issue:

:system
DSPSYSVAL QSRLNBR
DSPSYSVAL QMODEL

Only the first command, DSPSYSVAL QSRLNBR, will run. I am wondering if it has something to do with system and it altering stdin/stdout? I've tried all manner of system options without success.

Side note: I am not even sure if system outside a script is working correctly. For example, I believe the -q option should silence all output but it still returns results.

$ system -q 'DSPSYSVAL QMODEL'

Ok, i just pushed a fix (see below). Trick use a different file descriptor '3' to avoid collision with system. Hopefully this works, let me know.

#!shell

function chroot_setup {
  # copy needed PASE binaries
  action=""
  while read name <&3; do

... do stuff ...

  done 3<$1
}
