Sudo behaviour changed for SIGHUP in Red Hat Enterprise Linux 6.3

Issue

• 'nohup' no longer protects sudo process from being killed upon exit as of version 1.7.4p5-11.el6.x86_64 compared to version 1.7.2p2-9.el6.

Example

[test@host ~]# cat > /tmp/test.sh
#!/bin/sh

sleep 300 &


[test@server ~]$ ssh -t test@server "nohup sudo /tmp/test.sh"
Password:
nohup: ignoring input and appending output to `nohup.out'
Connection to server closed.

[test@server ~]$ ps -ef|grep sleep
test    760 29080  0 15:45 pts/4    00:00:00 grep sleep
