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 KERNEL-VER
DESCRIPTION
linux-check-removal is intended to be called from the prerm maintainer
scripts of Linux kernel packages.
The KERNEL-VER argument must be the kernel version string as shown by
uname -r and used in filenames, not the package version.
If the currently running kernel matches KERNEL-VER, 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 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.
