Code review comment for lp:~raharper/curtin/trunk.fix-bcache-sysfs-write-failures-on-remove

My only comments are that I really think it doesn't hurt to see the value of the error at a debug level.

I know you've had dis-interest in doing that before. but I just think its useful information.

except (IOError, OSError) as e:
    LOG.debug('bcache stop file %s not present, device removed: %s', bcache_stop, e)
