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 po‐
       tentially 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.
