NAME

ksplice-apply - Apply an on-disk Ksplice update to the running kernel


SYNOPSIS

ksplice-apply UPDATE_TARBALL


DESCRIPTION

ksplice-apply takes as input a Ksplice update tarball, as generated by ksplice-create(8), and it applies the update to the running binary kernel.

Specifically, ksplice-apply does the following:

  1. Inserts the ``primary'' module into the kernel.

  2. Inserts the ``helper'' module into the kernel (doing so applies the update).

  3. Removes the ``helper'' module from the kernel (that module is not needed after the update has been applied).

The update tarball used with ksplice-apply must have been generated for the running kernel's version.


OPTIONS

--debug=DEBUG_LEVEL

Applies the update with debugging output enabled. Recommended only for debugging. DEBUG_LEVEL should be an integer between 0 and 4. --debug=4 provides the most debugging information.

0

No debugging output.

1

Provides basic (pre-run matching and kernel stack check) debugging output.

2

Also provides full kernel stack check debugging output.

3

Also provides full pre-run matching debugging output.

4
