Description:
What does the following warning mean?

mkswap: /dev/mapper/NAME: warning: don't erase bootbits sectors on whole disk.
use -f to force

Manually testing mkswap -f on the luks device didn't break anything. "bootbits sectors" makes it sound risky but it doesn't seem to be.

Additional info:
* 2012.07.4-1
* /etc/crypttab
NAME /dev/DEV /dev/urandom swap,cipher=aes-xts-plain64:sha52,size=512


Steps to reproduce:
reboot

This is because mkswap has a protection against creating swap on a whole block device. I just pushed a fix from Matthew Monaco to git to avoid this warning. He also suggested a way to reduce the verbosity of the tools, so we no longer get the info message about encryption key etc.
