Hi Daniel,
can you comment on this by chance? I frankly don't use lxc-execute, and
I know you know of all sorts of special circumstances surrounding it...
For me,
cat > lxc.conf << EOF
lxc.utsname = beta
lxc.network.type = empty
lxc.rootfs = /
lxc.aa_profile = unconfined
EOF
lxc-execute -n foobar -f lxc.conf -- ps -ef
works fine, while
lxc-execute -n foobar -f lxc.donf -- /bin/sh
hangs - some tty session thing?
