Don't try to read freezer.state from the current directory
Don't try to read freezer.state from the current directory

If we try to pause a container on the system without freezer cgroups,
we can found that runc tries to open ./freezer.state. It is obviously wrong.

$ ./runc pause test
no such directory for freezer.state

$ echo FROZEN > freezer.state
$ ./runc pause test
container not running or created: paused
