    Heres an example, ebuilds are named package-version.ebuild and that version in the filename is used to define variables (such as $P here which is the name-version) to make new versions as simple as copying the ebuild with the new version in the filename.

    use_enable is used to generate the --enable-(option) or --disable-(option) as set by the user.

    For more info, see the devmanual. They’re nice relatively straightforward bash like PKGBUILDs, but with the repetitious stuff taken out.

    anything in particular I can clear up?

    blow by blow: first the request for an A record ( ipv4 address) for lemmy.ml is sent to a.root-servers.net ( one of several core name servers to the entire internet)

    they don’t reply with an A record, but instead a few NS ( nameserver) records for .ml and then in the additional section also give use the ipv4 and ipv6 addresses to those .ml name servers

    so we go ask those .ml servers again for an A record for lemmy.ml, they still don’t give us that A record, but instead say these ns.freenom.com name servers are responsible.

    we ask one of them and they finally give us that A record: lemmy.ml is 54.36.178.108 so your computer knows to connect to 54.36.178.108 when you ask for lemmy.ml.

    its the first and last two columns that are important. the second column is just how many seconds that information should be considered good for before asking again to make sure it hasn’t changed

    dns lookups ( what turns lemmy.ml into an address your computer can connect to) actually go right to left. first the root servers are asked, then they say go ask the ml servers and g, then they ask the lemmy.ml servers.

    in practice, usually unless otherwise configured your isp’s name servers are asked first; if someone else has recently asked for the same site it remembers what the answer was and just gives the same to you.

    eh, its true if you want it to be signed by microsoft, which some projects have forked out for, buut it was put into the spec for x86_64 systems that users can replace the keys. so you can make your own keys, and if you want to dual boot add microsoft’s keys to the ok to boot list.

    one of the signed projects is a shim that lets you approve whatever you want more or less; pretty much everything that talks about MOK refers back to this shim. many distributions use this shim
