Hi all,

In my TS7200, I made an init script which starts some processes to
take webcam pictures, read smartcards, scan fingerprints, etc. The
script (/etc/init.d/dex.sh) is like this :

utlscansmart-mifare &
utlscanfinger &
utlwebcam &
utlmodem &

To add the init script I used :
update-rc.d /etc/init.d/dex.sh defaults 99

In TS 7200 with kernel 2.4 when my init script ends the processes
have their ppid changed to 1 and they continue running. In Ts7260 and
TS kernel 2.6.21, when my init script ends all the child processes
die with it. Is there a kernel configuration to prevent the init
child processes from dieing with their parent ?

Best,
Fábio Vaz.
