  1. #TIL (Today I Learned) about Linux that if you need the file `/etc/crypttab` (because you have more than just one encrypted partition) and you unlock the non-root partitions using keyfiles rather than with a passphrase, then you should write the option `nofail` into the fourth column of `/etc/crypttab`.

    Adding this option shortens the boot process. In other words, it makes your computer boot faster.

    Decrypting a partition using a keyfile can take a few seconds, due to the way key derivation functions (such as PBKDF2) work. You don't want the cryptsetup service to be blocked while the non-root partitions get decrypted.
