.SH NAME

semodule \- Manage SELinux policy modules.

.SH SYNOPSIS

|
|
.SH DESCRIPTION
|
|
.PP
|
|
semodule is the tool used to manage SELinux policy modules,
|
|
including installing, upgrading, listing and removing modules.
|
|
semodule may also be used to force a rebuild of policy from the
|
|
module store and/or to force a reload of policy without performing
|
|
any other transaction. semodule acts on module packages created
|
|
by semodule_package. Conventionally, these files have a .pp suffix
|
|
(policy package), although this is not mandated in any way.
|
|
|
|
.SH "MODES"
|
|
.TP
|
|
.B \-R, \-\-reload
|
|
force a reload of policy
|
|
.TP
|
|
.B \-B, \-\-build
|
|
force a rebuild of policy (also reloads unless \-n is used)
|
|
.TP
|
|
.B \-\-refresh
|
|
Like \-\-build, but reuses existing linked policy if no changes to module
|
|
files are detected (by comparing with checksum from the last transaction).
|
|
One can use this instead of \-B to ensure that any changes to the module
|
|
store done by an external tool (e.g. a package manager) are applied, while
|
|
automatically skipping the module re-linking if there are no module changes.
|
|
.TP
|
|
.B \-D, \-\-disable_dontaudit
|
|
Temporarily remove dontaudits from policy. Reverts whenever policy is rebuilt
|
