Bug#954200: DI encrypted LVM, discard option crypttab file

[john doe <johndoe65534@mail.com>]

Package: debian-installer
Version: debian-10.3.0-amd64-netinst.iso

After installing debian-10.3.0-amd64-netinst.iso with encrypted LVM, the
crypttab file is populated with the discard' option in the fourth field.

According to (1), the discard option has security implication:

"discard
Allow discard requests to be passed through the encrypted block device.
This improves performance on SSD storage but has security implications."


I would suggest that the debian-installer populates the first two
mandatory fields of '/etc/crypttab'.
