  • Interesting,
    non-scientific speed test:

    kernel 6.1.0-37-amd64:

    $ time for i in $(seq 1 100000); do cat /proc/sys/kernel/random/uuid > /dev/null; done
    
    real    3m53,388s
    user    1m37,366s
    sys     2m13,847s
    
    $ for i in $(seq 1 100000); do cat /proc/sys/kernel/random/uuid ; done | wc -l
    100000
    

    vs. uuid 1.6.2-1.5+b11:

    $ time for i in $(seq 1 100000); do uuid -v4 > /dev/null; done
    
    real    4m44,854s
    user    1m37,867s
    sys     3m4,414s
    
    $ for i in $(seq 1 100000); do uuid -v4 ; done | wc -l
    100000
    

    EDIT: I’m blind (wrong result).





  • After 12 years (me converting in 2013 to systemd on Arch BTW)
    I can say we finally have standardization between major distributions.
    OpenRC, SysV or Upstart…? How to do things…

    Real boot time improvement.
    Real multiple instances of the same service (service-name@xyz.sevice).
    Drop-in overrides. Builtin DNS cache, timesync, syslog, cron (kinda, timers have new syntax),
    cgroups, boot manager, network manager, containers, and more…

    Not a Unix or KISS philosophy, but come on, we need a fresh blood.
    There is no “next gen” kernel/operating system in the horizon.

    I have Devuan and PostmarketOS (Alpine with desktop environment),
    I feel like a caveman. Things which are easy to do in systemd, in OpenRC are not trival.
    OpenRC in Gentoo is not the same as in Devuan.

    Also, more and more software is systemd-centric.

    However.
    I encourage you to discover Linux without systemd first (extra layer of abstraction may be difficult during learning).
