More systemd commands

  • Boot critical chain
    systemd-analyze critical-chain <unit>

    Show the serialized dependency chain that actually delays boot; more honest than blame

  • Boot timeline SVG
    systemd-analyze plot > boot.svg

    Render full parallel boot timeline as an SVG to spot serialized stalls visually

  • Drop-in override
    systemctl edit <unit> # writes /etc/systemd/system/<unit>.d/override.conf

    Patch a unit via drop-in without touching the vendor file; use --full to fork the whole unit

  • Reload unit files
    systemctl daemon-reload

    Reload unit files after editing; note: required after manual edits or systemctl warns of stale config

  • Mask a unit
    systemctl mask <unit> && systemctl unmask <unit>

    Mask symlinks a unit to /dev/null so it cannot start even as a dependency; stronger than disable
