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