There is also a hang when caused by grep when $IMAGE is not set :
# bash -x /usr/sbin/ltsp-update-image
[...]
++ grep /etc/inetd.conf
++ grep -v '^#'
[hang here]
The problem is :
---> if [ -n "$(grep ${IMAGE} /etc/inetd.conf|grep -v "^#")" ];then
Then, if $IMAGE is empty, the first grep waits for input
The architecture I use is i386, but I renamed the directory i386 to
i386-dev for development purpose. Image are not generated until I set
the CHROOT variable.
The hang could be avoided if variables were validated.
