Override kernel default for dm-crypt mappings of LUKS1 encrypted
volumes via flag put in /etc/crypttab file. This change should affect
only newly created encrypted storage based on LUKS1 format during
installation.
== Detailed Description ==
User base of Fedora distribution with SSDs grows steadily and while
the argument for kernel default setting not to enable the discard is
still strong one it doesn't change the fact that vast majority of
users (with SSDs) doesn't want to sacrifice better performance of
drive with discard/trim enabled for the sake of secrecy.
How is SSD being detected?
