linux-check-removal - check whether removal of a kernel is safe
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
Name of the preferred debconf front-end. If set to
noninteractive, debconf prompts are disabled and
linux-check-removal always quietly succeeds.
Name of the package to be removed, automatically set by dpkg.
linux-check-removal and this manual page were written by Ben
Hutchings as part of the Debian linux-base package.
