When I try to run Dagger on a particular host, it fails as such:
mkdir: can't create directory '/sys/fs/cgroup/init': Read-only file system
One other question in here mentions a problem with cgroup permission. It's specific to Rancher, but I thought I'd try the suggested solution anyways (add rc_cgroup_mode="unified" to /etc/rc.conf) - no dice (yes, I rebooted).
Other containers run fine.
