* Tweak output of the loader variableWarner Losh2020-09-251-12/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the DEVICE_PATH is <= 4 that means it's effectively empty. I have a laptop that has a BIOS that likes to generate these: 8be4df61-93ca-11d2-aa0d-00e098032b8c-Boot2001 0000: 01 00 00 00 04 00 45 00 46 00 49 00 20 00 55 00 0010: 53 00 42 00 20 00 44 00 65 00 76 00 69 00 63 00 0020: 65 00 00 00 7f ff 04 00 52 43 which now decodes as 8be4df61-93ca-11d2-aa0d-00e098032b8c-Boot2001 * EFI USB Device Empty path Option: 0000: 52 43 which matches my hand-decode. Add an extra newline after Option: to make it look nice. I suspect that these entries really should be VenHw entries instead, but my ability to change that is NIL, so cope with them as best we can. efibootmgr(8)'s output is fine and doesn't need adjusting.

* Regularize the Netflix copyrightWarner Losh2019-02-041-1/+0
| | | | | | | | | | | | | | | Use recent best practices for Copyright form at the top of the license: 1. Remove all the All Rights Reserved clauses on our stuff. Where we piggybacked others, use a separate line to make things clear. 2. Use "Netflix, Inc." everywhere. 3. Use a single line for the copyright for grep friendliness. 4. Use date ranges in all places for our stuff. Approved by: Netflix Legal (who gave me the form), adrian@ (pmc files) Notes: svn path=/head/; revision=343755
