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 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.
