9 Clevis provides unlockers for LUKS volumes which can use LUKS policy:
10
11 · clevis-luks-unlock - Unlocks manually using the command line.
12
13 · dracut - Unlocks automatically during early boot.
14
15 · systemd - Unlocks automatically during late boot.
16
17 · udisks2 - Unlocks automatically in a GNOME desktop session.
18
19 Once a LUKS volume is bound using clevis luks bind, it can be unlocked
20 using any of the above unlockers without using a password.
21
23 You can unlock a LUKS volume manually using the following command:
24
25 $ sudo clevis luks unlock -d /dev/sda
26
27 For more information, see clevis-luks-unlock(1).

30 If Clevis integration does not already ship in your initramfs, you may
31 need to rebuild your initramfs with this command:
32
33 $ sudo dracut -f
34
35 Once Clevis is integrated into your initramfs, a simple reboot should
36 unlock your root volume. Note, however, that early boot integration
37 only works for the root volume. Non-root volumes should use the late
38 boot unlocker.
39
40 Dracut will bring up your network using DHCP by default. If you need to
41 specify additional network parameters, such as static IP configuration,
42 please consult the dracut documentation.
43
45 You can enable late boot unlocking by executing the following command:
46
47 $ sudo systemctl enable clevis-luks-askpass.path
48
49 After a reboot, Clevis will attempt to unlock all _netdev devices
50 listed in /etc/crypttab when systemd prompts for their passwords. This
51 implies that systemd support for _netdev is required.
52
54 When the udisks2 unlocker is installed, your GNOME desktop session
55 should unlock LUKS removable devices configured with Clevis
56 automatically. You may need to restart your desktop session after
57 installation for the unlocker to be loaded.
