CRYPTSETUP-CONFIG(8) Maintenance Commands CRYPTSETUP-CONFIG(8)
NAME
cryptsetup-config - set permanent configuration options (store to LUKS
header)
SYNOPSIS
cryptsetup config <options> <device>
DESCRIPTION
Set permanent configuration options (store to LUKS header). The config
command is supported only for LUKS2.
The permanent options can be --priority to set priority (normal,
prefer, ignore) for keyslot (specified by --key-slot) or --label and
--subsystem.
<options> can be [--priority, --label, --subsystem, --key-slot,
--header, --disable-locks].
OPTIONS
--key-slot, -S <0-N>
For LUKS operations that add key material, this option allows you
to specify which key slot is selected for the new key.
The maximum number of key slots depends on the LUKS version. LUKS1
can have up to 8 key slots. LUKS2 can have up to 32 key slots based
on key slot area size and key size, but a valid key slot ID can
always be between 0 and 31 for LUKS2.
--header <device or file storing the LUKS header>
Use a detached (separated) metadata device or file where the LUKS
header is stored. This option allows one to store ciphertext and
LUKS header on different devices.
For commands that change the LUKS header (e.g. luksAddKey), specify
the device or file with the LUKS header directly as the LUKS
device.
--disable-locks
Disable lock protection for metadata on disk. This option is valid
only for LUKS2 and ignored for other formats.
WARNING: Do not use this option unless you run cryptsetup in a
restricted environment where locking is impossible to perform
(where /run directory cannot be used).
--priority <normal|prefer|ignore>
Set a priority for LUKS2 keyslot. The prefer priority marked slots
are tried before normal priority. The ignored priority means, that
slot is never used, if not explicitly requested by --key-slot
option.
--label <LABEL> --subsystem <SUBSYSTEM>
Set label and subsystem description for LUKS2 device. The label and
subsystem are optional fields and can be later used in udev scripts
for triggering user actions once the device marked by these labels
is detected.
--batch-mode, -q
Suppresses all confirmation questions. Use with care!
If the --verify-passphrase option is not specified, this option
also switches off the passphrase verification.
--debug or --debug-json
Run in debug mode with full diagnostic logs. Debug output lines are
always prefixed by #.
If --debug-json is used, additional LUKS2 JSON data structures are
printed.
--version, -V
Show the program version.
--usage
Show short option help.
--help, -?
Show help text and default parameters.
REPORTING BUGS
Report bugs at cryptsetup mailing list <cryptsetup@lists.linux.dev> or
in Issues project section
<https://gitlab.com/cryptsetup/cryptsetup/-/issues/new>.
Please attach output of the failed command with --debug option added.
