Unlock a Veracrypt/Truecrypt partition which uses a keyfile with a passphrase from /etc/crypttab

Hi! I have a Veracrypt (/Truecrypt) volume, which I can successfully
unlock manually by providing a key file and passphrase:

    # cryptsetup --type tcrypt --key-file /.keyfile open /dev/nvme0n1p5 shared
    Enter passphrase for /dev/nvme0n1p5:

Only root has `rw` on the key file, a binary file of 64 bytes.

    # ls -l /.keyfile
    -rw------- 1 root root 64 aug 21 08:09 /.keyfile
    # file /.keyfile
    /.keyfile: data
    # du -b /.keyfile
    64 /.keyfile

Is there a way to unlock a Veracrypt (/Truecrypt, `/dev/nvme0n1p5` in
my case) partition that uses a key file with a password in
`/etc/crypttab`?

I have tried constructing a file with the structure
`{passphrase}{newline}{key file contents}` and manually using it to
unlock as above, but I still got the passphrase question. To create
that file, I did the following:

    # echo 'mypassword' > /.keyfile_psw
    # cat /.keyfile >> /.keyfile_psw
