2727: turbo/zol-bug-report - Initial version of a ZoL "report issue" …

…script.

+ Check to make sure we're root (or have root access - sudo).
+ Use 'free -m' instead of 'free -h' which don't seem to be available everywhere.
+ Get the whole dmesg log, just for completeness
+ Modify SPL/ZFS version retrieval.
