CHKBOOT(8)

CHKBOOT 💖 (section 8, System Manager's Manual)

okay bestie, so this is chkboot — the little system-manager bestie that keeps an eye on your unencrypted /boot partition for you. yes, that's the manual name, section 8, and yes, we're getting into it. 🎀

✨ NAME ✨

chkboot — checks for unwanted modification on unencrypted /boot partition 👀

---

🌸 SYNOPSIS 🌸

chkboot [OPTIONS]

---

🦋 DESCRIPTION 🦋

She checks for any modification to your boot files since the last time she ran. like, literally any. the way she just knows?? 💅

🎀 the options, bestie

• --update, -u — mark changes as valid. the next run of chkboot will not warn about differences. so you're basically telling her "yeah girl i know, it's fine, we move on" 🫶
• --help, -h — show this help message and exit. iconic behaviour, honestly.

chkboot runs at system startup to check for boot files modifications. you'll be warned upon login if any are found. not me finding out at login that something shifted in /boot 😭

kernel upgrades are automatically marked as valid. no notes. 👑

configurations, such as boot partition, can be edited in:

/etc/default/chkboot

---

💜 EXAMPLES 💜

acknowledge a detected change after chkboot has displayed a warning:

chkboot

clear valid modifications made by users:

chkboot -u

---

🌈 SEE ALSO 🌈

• man chkboot-check and man chkboot-desktopalert — go read those too, iykyk ✨

---

💀 BUGS 💀

• GPT partitions are not supported. as chkboot will continue to work, it will not report changes in GPT headers (only protective MBR). so like... she's still showing up to the function, she's just not clocking that one specific thing. fr fr. 🙈
