linux-check-removal (1) Linux Manual Page
NAME
linux-check-removal – check whether removal of a kernel is safe
SYNOPSIS
-
linux-check-removalVERSION
DESCRIPTION
linux-check-removal is intended to be called from the prerm
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-removalalways quietly succeeds. - DPKG_MAINTSCRIPT_PACKAGE
- Name of the package to be removed, automatically set by dpkg.
