LINUX-CHECK-REMOVAL(1)

✨ LINUX-CHECK-REMOVAL(1) ✨

okay so bestie, this is the manual page for linux-check-removal 🧚 it's from the General Commands Manual section, and it's giving "check before you delete the kernel" energy 💅

🌸 NAME 🌸

linux-check-removal — check whether removal of a kernel is safe 🫶

💜 SYNOPSIS 💜

linux-check-removal KERNEL-VER

🦋 DESCRIPTION 🦋

okay so linux-check-removal is built to be called from the prerm maintainer scripts of Linux kernel packages. it's the bouncer at the door, no cap 🚪🔥

the KERNEL-VER argument has to be the kernel version string you get from uname -r, the one used in filenames. it is not the package version, so don't mix them up bestie 🙈

if the currently running kernel matches KERNEL-VER, the command normally asks the user to confirm, because removing the kernel you're running on is potentially dangerous 💀 if they say abort, it fails. there are two exceptions though, so pay attention:

• if you're in a chroot or container, it assumes the running kernel has nothing to do with any installed kernel package, so it quietly succeeds every time ✨
• if debconf prompts are disabled, it warns you if you're removing the running kernel, but it always succeeds anyway 🌈

🎀 ENVIRONMENT VARIABLES 🎀

• DEBIAN_FRONTEND — this is the debconf front-end you'd like to use. if it's set to noninteractive, debconf prompts are turned off and linux-check-removal always quietly succeeds 🫧
• DPKG_MAINTSCRIPT_PACKAGE — the name of the package being removed. dpkg sets this automatically, so you don't have to lift a finger 💖

🧚 AUTHOR 🧚
