Use highlighted warning only for possibility of data loss or serious security issues.

No need to scary people everywhere :)

@@ -31,7 +31,7 @@ The _reencrypt_ action reencrypts data on the LUKS device in-place.
You can regenerate *volume key* (the real key used in on-disk encryption unlocked by passphrase), *cipher*, *cipher mode* or *encryption sector size* (LUKS2 only).
*WARNING:* If you need to use both luksChangeKey and reencrypt (e.g., to recover from a leak), you need to use them in that order to avoid leaking the new volume key.
If you need to use both luksChangeKey and reencrypt (e.g., to recover from a leak), you need to use them in that order to avoid leaking the new volume key.
The reencryption process may be safely interrupted by a user via SIGINT signal (ctrl+c).
The same applies to the SIGTERM signal (i.e., issued by systemd during system shutdown).

@@ -563,7 +563,7 @@ Albeit Linux kernel 5.7 added TRIM support for standalone dm-integrity devices,
Some integrity modes require two independent keys (a key for encryption and authentication).
Both these keys are stored in one LUKS keyslot.
*WARNING:* All support for authenticated modes is experimental, and only some modes are available now.
Support for authenticated modes is experimental, and only some modes are available now.
Note that very few authenticated encryption algorithms are suitable for disk encryption.
You also cannot use CRC32 or other non-cryptographic checksums (other than the special integrity mode "none").
If, for some reason, you want to have integrity control without using authentication mode, then you should separately configure dm-integrity independently of LUKS2.
