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

## SYNOPSIS


       **linux-check-removal _**VERSION_

## DESCRIPTION
       **linux-check-removal  **is intended to be called from the prerm maintainer scripts of Linux ker‐
       nel packages.

       The _VERSION_ argument must be the kernel version string as shown by **uname -r **and used in file‐
       names.

       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 al‐
         ways 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.

## AUTHOR
       **linux-check-removal  **and this manual page were written by Ben Hutchings as part of the Debian
       **linux-base **package.
