LINUX-CHECK-REMOVAL(1)					LINUX-CHECK-REMOVAL(1)

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 pack‐
	 age 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 noninterac‐
	      tive,  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.
