NAME¶
ksplice-undo - Undo a Ksplice update that has been applied to the running kernel
SYNOPSIS¶
ksplice-undo [
OPTIONS]
KSPLICE_ID
DESCRIPTION¶
ksplice-undo takes as input a Ksplice identification tag, as reported by
ksplice-view(8), and it reverses that update within the running binary
kernel.
OPTIONS¶
- --debug
- Reverses the update with debugging output enabled. Recommended only for
debugging.
- --debugfile=filename
- Sets the location where debugging output should be saved. Implies
--debug.
- --raw-errors
- Print only raw error information designed to be machine-readable on
standard error (standard output is still intended to be human-readable).
If ksplice-undo fails due to an error from the Ksplice kernel
modules, the first line on standard error will be a Ksplice abort
code (see the Ksplice source code for documentation on these codes).
Further lines will vary depending on the abort code. If
ksplice-undo fails for any other reason, it will output the line
"OTHER\n", followed by a human-readable failure message, to
standard error.
