That won't help (looking at /boot/loader.rc) as my lua updated system still has: borg.lerctr.org /home/ler $ more /boot/loader.rc \ Loader.rc \ $FreeBSD: head/stand/i386/loader/loader.rc 331326 2018-03-21 22:01:51Z ke= vans $ \ \ Includes additional commands include /boot/loader.4th include /boot/efi.4th try-include /boot/loader.rc.local \ Reads and processes loader.conf variables initialize maybe-efi-resizecons \ Tests for password -- executes autoboot first if a password was defined check-password \ Load in the boot menu include /boot/beastie.4th \ Start the boot menu beastie-start borg.lerctr.org /home/ler $<Paste> so it still looks forth'ish, but it's using lua. >=20 > --=20 > John Baldwin > _______________________________________________ > freebsd-current@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" --=20 Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 E-Mail: ler@lerctr.org US Mail: 5708 Sabbia Drive, Round Rock, TX 78665-2106 --lno55kmn4s22nhzj Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQHABAABCgCqFiEEHjgknedhWzvJgwVzaXyZsatIp30FAlt5oxwsFIAAAAAAFQAO cGthLWFkZHJlc3NAZ251cGcub3JnbGVyQGxlcmN0ci5vcmdfFIAAAAAALgAoaXNz dWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDFFMzgy NDlERTc2MTVCM0JDOTgzMDU3MzY5N0M5OUIxQUI0OEE3N0QACgkQaXyZsatIp30I awgAhycKYirfaHzbsOwalvzZPTRVk6jdsq1aafN3laAaq4LlPXHmn8i7IO97n5UN 6pXUB/PdDWpH5LtVbkW4fvleJSPqjA243slOXUamAsjPoqAVUVCPXZNX9m6JIpxV +TLmTEXVccPuC6590g8S8haaHae3+8us0kx7E9ofUvf2HlbGV0evcKeoBdDSGIQP pT8FQYFubv6d8N9ArfxFN1VPif74sa0fr4A8K+HHkVwreA4vOoowZfBPIo84St+L op3wpcPsFTk8CWm2ADoAYVzo+p+J4OskxUe41KsLTpIjYojLtN8p1Mh0l0ipAXBY 1EC0kxXvhfarDutkf1soHJkKNg== =IFY2 -----END PGP SIGNATURE----- --lno55kmn4s22nhzj--
