NAME
linux-check-removal - check whether removal of a kernel is safe
SYNOPSIS
linux-check-removal KERNEL-VER
DESCRIPTION
linux-check-removal is intended to be called from the prerm maintainer scripts of Linux kernel packages.
The KERNEL-VER argument must be the kernel version string as shown by uname -r and used in filenames, not
the package version.
If the currently running kernel matches KERNEL-VER, 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.
