uname -v gives me the version level of the booted environment.

How can I get the version level of an environment without booting that environment?

In the example below, a boot environment (BE) is mounted at a temporary path by TrueOS Desktop. I can access relevant parts of the file system but I don't know where to seek the required information:

Does strings /tmp/BE-.../boot/kernel/kernel | egrep ^FreeBSD solve your issue?
