LINUX-CHECK-REMOVAL(1)                 General Commands Manual                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 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.
