New Revision: 349217
URL: https://svnweb.freebsd.org/changeset/base/349217
Log:
Tell loader to ignore newer features enabled on the root pool.
There are many new features in ZoF. Most, if not all, do not effect read only
usage.
Encryption in particular is enabled at the pool level but used at the dataset
level.
The loader obviously will not be able to boot if the boot dataset is
encrypted, but
should not care if some other dataset in the root pool is encrypted.
