  • Fun With systemd-analyze

    Another interesting little command in the systemd suite is
    systemd-analyze <https://www.freedesktop.org/software/systemd/man/latest/systemd-analyze.html>: this one does a bunch of things, including helping to track down
    bottlenecks in your boot or session-login sequence, check the
    integrity of config and security settings, test out evaluations of
    expressions that might be used in config files, act as a quick
    reference to certain kinds of system numeric codes, and also show you information about your system’s TPM2 capabilities.

    Just one thing: watch out for the use of the “dot” command, as shown
    in some examples, to format various call graphs in pretty formats: it
    can be quite slow, taking about a minute on my machine.

    Of course, this isn’t the fault of systemd ...

    It has grown in options. I knew "blame", "critical-chain", "plot", I think.
