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.
