7 cesses
8
10 Security-Enhanced Linux secures the run_init processes via flexible
11 mandatory access control.
12
13 The run_init processes execute with the run_init_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep run_init_t
20
21
22
24 The run_init_t SELinux type can be entered via the run_init_exec_t file
25 type.
26
27 The default entrypoint paths for the run_init_t domain are the follow‐
28 ing:
29
30 /usr/sbin/run_init
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 run_init policy is very flexible allowing users to setup their run_init
40 processes in as secure a method as possible.
41
42 The following process types are defined for run_init:
43
44 run_init_t
45
46 Note: semanage permissive -a run_init_t can be used to make the process
47 type run_init_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required.
54 run_init policy is extremely flexible and has several booleans that al‐
55 low you to manipulate the policy and run run_init with the tightest ac‐
56 cess possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type run_init_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

113 SELinux requires files to have an extended attribute to define the file
114 type.
115
116 You can see the context of a file using the -Z option to ls
117
118 Policy governs the access confined processes have to these files.
119 SELinux run_init policy is very flexible allowing users to setup their
120 run_init processes in as secure a method as possible.
121
122 STANDARD FILE CONTEXT
123
124 SELinux defines the file context types for the run_init, if you wanted
125 to store files with these types in a different paths, you need to exe‐
126 cute the semanage command to specify alternate labeling and then use
127 restorecon to put the labels on disk.
128
129 semanage fcontext -a -t run_init_exec_t '/srv/run_init/content(/.*)?'
130 restorecon -R -v /srv/myrun_init_content
131
132 Note: SELinux often uses regular expressions to specify labels that
133 match multiple files.
134
135 The following file types are defined for run_init:
136
137
138
139 run_init_exec_t
140
141 - Set files with the run_init_exec_t type, if you want to transition an
142 executable to the run_init_t domain.
143
144
145
146 Note: File context can be temporarily modified with the chcon command.
147 If you want to permanently change the file context you need to use the
148 semanage fcontext command. This will modify the SELinux labeling data‐
149 base. You will need to use restorecon to apply the labels.
150
151
153 semanage fcontext can also be used to manipulate default file context
154 mappings.
155
156 semanage permissive can also be used to manipulate whether or not a
157 process type is permissive.
158
159 semanage module can also be used to enable/disable/install/remove pol‐
160 icy modules.
161
162 semanage boolean can also be used to manipulate the booleans
163
164
165 system-config-selinux is a GUI tool available to customize SELinux pol‐
166 icy settings.
