I use cryptsetup with working discard since F16. In F16 it was necessary, to manuell build cryptsetup. But to enable the discard option, I use a workaround with the dm-table. And now in F17, I'm looking for a easier method and to change the cryptroot-ask.sh doesn't work.

Thank you, you have found what I was looking for.

Have you open a bug report to dracut about this?

You need to run "dracut -f" after having modified cryptroot-ask.sh

If you're asking me, then no I haven't. I considered from the comment in the file that it is a known issue that some command line arguments for cryptsetup are not available through crypttab with dracut. I should probably get around to filing a bug report anyway.
