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 kernel packages.

       The VERSION argument must be the kernel version string as shown by  un-
       ame -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:

       o 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

       o 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  al-
              ways quietly succeeds.
       DPKG_MAINTSCRIPT_PACKAGE
              Name of the package to be removed, automatically set by dpkg.
