[pkg-cryptsetup-devel] Bug#648868: cryptsetup: Please add support for allow-discards option in crypttab

[intrigeri+debian at boum.org]

Package: cryptsetup
Severity: wishlist
Tags: patch

Hi,

cryptsetup 1.4.0 brings support for --allow-discards, which is useful
on SSD storage devices, although it comes with security risks that
must be assessed.

The attached patch, prepared and tested against the current packaging
SVN repo (rev. 897), adds support for an allow-discards option in
crypttab, that translates into passing --allow-discards to cryptsetup.
This patch also updates the documentation accordingly. Please review.

(I'll mark this bug as blocked by #647851 as soon as I get its number.)

Regards,
