Converting to dracut from mkinitcpio with LUKS encrypted file systems

[solino]

Hello: I was reading the guide that appears in Dracut Discovery in which they indicate that “If you have any LUKS encrypted file systems, you must create a dracut drop-in config for that. Create the file /etc/dracut.conf.d/encryption.conf with the following content”. However, in Archwiki they indicate “dracut is easy to use and typically does not require user configuration, even when using non-standard setups, like LVM on LUKS”.

This are my partitions:

My question is if it is necessary to create the encryption.conf file as it appears in Discovery

If memory serves, needing to add the device is no longer needed.

However, if you are using a keyfile to unlock the device, you should add that keyfile if the initrd is being stored in an encrypted location.

Thank you Dalto for your quick response. I think that in my case, since I installed EndeavourOs in 2021 on a laptop encrypting the entire system, I will need to create the file /etc/dracut.conf.d/encryption.conf with the following content: install_items+=" /etc/crypttab /crypto_keyfile.bin "
I don’t use physical swap but zram, so I guess I don’t have to do anything else.

I wish you a good day
