Severity: minor

Hello,

The crypttab(5) man page has an example labeled "Encrypted swap device"
that should be updated so it does not print warnings.


## Summary

The example should be updated to this (add "plain", remove "hash=sha1"):

cswap /dev/sda6 /dev/urandom plain,cipher=aes-xts-plain64,size=256,swap

Instead of this:

cswap /dev/sda6 /dev/urandom cipher=aes-xts-plain64,size=256,hash=sha1,swap


## Justification

Otherwise, cryptsetup prints these warnings:

```
# cryptdisks_start cswap
Starting crypto disk...
cryptsetup: WARNING: cswap: couldn't determine device type, assuming default 
(plain).
cswap (starting)...
WARNING: The --hash parameter is being ignored in plain mode with keyfile 
specified.
cswap (started)...done.
```


Thank you for your work on cryptsetup.

Owen
