No it sounds unexpected. Would you be able to code the above into a
little test script to reproduce? (something like
sudo lxc-create -t ubuntu -n x1
sudo lxc-start -n x1 -d
sudo nohup lxc-wait -s STOPPED -n x1 > /tmp/outout 2>&1 &
pid=$!
sudo lxc-sttach -n x1 -- poweroff
tail /tmp/outout
ps -p $pid && echo "lxc-wait still running - FAIL"
ps -p $pid || echo "lxc-wait exited - PASS"
)
Also please tell us which distro+release you're on and the exact package
or upstream git version (there have been very recent changes...) Is
lxc-wait a script or a program in yours? (which lxc-wait; file `which
lxc-wait`)
thanks,
