.SH DESCRIPTION
|

.PP
|
||||
-This utility is used to generate file context configuration entries
|
||||
-for user home directories based on their default roles and is run when
|
||||
-building the policy. Specifically, it replaces the
|
||||
-.B HOME_ROOT, HOME_DIR,
|
||||
-and
|
||||
-.B ROLE
|
||||
-macros in .fc files with generic and user-specific values. It reads
|
||||
-the list of users from the
|
||||
-.I <<FILECONTEXTDIR>>/users
|
||||
+This utility is used to generate file context configuration entries for
|
||||
+user home directories based on their default roles and is run when building
|
||||
+the policy. It can also be run when ever the
|
||||
+.I /etc/selinux/<<SELINUXTYPE>>/users/local.users
|
||||
+file is changed
|
||||
+Specifically, we replace HOME_ROOT, HOME_DIR, and ROLE macros in the
|
||||
+.I /etc/selinux/<<SELINUXTYPE>>/contexts/files/homedir_template
|
||||
+file with generic and user-specific values.
|
||||
+.I local.users
|
||||
file. If a user has more than one role in
|
||||
-.I <<FILECONTEXTDIR>>/users,
|
||||
+.I local.users,
|
||||
.B genhomedircon
|
||||
uses the first role in the list.
|
||||
.PP
|
||||
If a user is not listed in
|
||||
-.I <<FILECONTEXTDIR>>/users,
|
||||
+.I local.users,
|
||||
.B genhomedircon
|
||||
assumes that the user's home dir will be found in one of the
|
||||
-HOME_ROOTs. When looking for these users,
|
||||
+HOME_ROOTs.
|
||||
+When looking for these users,
|
||||
.B genhomedircon
|
||||
only considers real users. "Real" users (as opposed
|
||||
to system users) are those whose UID is greater than or equal
|
||||
.I STARTING_UID
|
||||
(default 500) and whose login shell is not "/sbin/nologin", or
|
||||
-"/bin/false". Users who are explicitly defined in
|
||||
-.I <<FILECONTEXTDIR>>/users
|
||||
+"/bin/false".
|
||||
+.PP
|
||||
+Users who are explicitly defined in
|
||||
+.I local.users,
|
||||
are always "real" (including root, in the default configuration).
