NAME¶

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

SYNOPSIS¶

DESCRIPTION¶

linux-check-removal is intended to be called from the prerm maintainer scripts of Linux kernel packages. The VERSION argument must be the kernel version string as shown by uname -r and used in filenames. If the currently running kernel matches VERSION, linux-check-removal normally prompts the user to confirm this potentially dangerous action and fails if the user chooses to abort. There are two exceptions to this behaviour:

•

If the current environment is a chroot or container, it is assumed that the running kernel is independent of any installed kernel package and the command always quietly succeeds

•

If debconf prompts are disabled, the command warns if removing the running kernel but always succeeds

ENVIRONMENT VARIABLES¶

DEBIAN_FRONTEND

Name of the preferred debconf front-end. If set to noninteractive, debconf prompts are disabled and linux-check-removal always quietly succeeds.

DPKG_MAINTSCRIPT_PACKAGE

Name of the package to be removed, automatically set by dpkg.
