.TH update-kernel 8 "May 15, 2023" "update-kernel 8"
.SH NAME
update-kernel \- Linux kernel update tool
.SH SYNOPSIS
.B update-kernel
[options]
.SH DESCRIPTION
update\-kernel \- script to conveniently update kernel and modules.
.PP
It works by installing a new package set along with the existing kernel.
The old kernel is kept so that you don\'t end up without a kernel guaranteed
to boot (your good old one); by default, it will look for the most recent
package of the same flavour (e.g. "std\-def") and try to install all the
same modules as already installed for that.
