14 pam_console_apply is a helper executable which sets or resets permis‐
15 sions on device nodes.
16 If /var/run/console.lock exists, pam_console_apply will grant permis‐
17 sions to the user listed therein. If the lock file does not exist,
18 permissions are reset according to defaults set in console.perms files,
19 normally configured to set permissions on devices so that root owns
20 them.
21
22 When initializing its configuration it first parses the /etc/secu‐
23 rity/console.perms file and then it searches for files ending with the
24 .perms suffix in the /etc/security/console.perms.d directory. These
25 files are parsed in the lexical order in "C" locale. Permission rules
26 are appended to a global list, console and device class definitions
27 override previous definitions of the same class.
28
30 -c Load other console.perms file than the default one.
31
32 -f Load other fstab file than the default one (/etc/fstab).
33
34 -r Signals pam_console_apply to reset permissions. The default is
35 to set permissions so that the user listed in /var/run/con‐
36 sole.lock has access to the devices, and to reset permissions if
37 no such file exists.
38
39 -t Use <tty> to match console class in console.perms file. The de‐
40 fault is tty0.
41
42 -s Write error messages to the system log instead of stderr.
43
44 -d Log/display messages useful for debugging.
45
46 The optional <device file> arguments constrain what files should be af‐
47 fected by pam_console_apply. If they aren't specified permissions are
48 changed on all files specified in the console.perms file.
