Public bug reported:
On a fresh Ubuntu 16 release, commands started by lxc-attach such as dd
are being killed, and lxc-attach return a zero status.
This scenario is working on Ubuntu 15 with previous lxc release, but not
on new LXC 2.0.0 (same issue on 2.0.1 too)
sudo apt-get -y install lxc
sudo lxc-create -n utest -t ubuntu -- -a amd64 -b $USER
sudo lxc-start -d --name utest
sudo lxc-attach -n container -- dd if=/dev/zero of=/tmp/foo bs=1M count=10
2>/tmp/bar
sudo lxc-attach -n utest_bizio_tests -- ls -lh /tmp/foo
-rw-r--r-- 1 root root 0 May 18 05:46 /tmp/foo
Might be related to bug 1553097
NOTE: Sometimes the "sudo lxc-attach -n utest_bizio_tests -- ls -lh
/tmp/foo" ALSO does not return anything (no output)
I'm available for any additional info.
