I have followed the following instructions:
How can I install dual-boot encrypted Ubuntu with LUKS?
I have created a 4G swap partition on the encrypted LVM partition according to the last link, but not sure if the entry in the / etc / crypttab file should be used.
When I run:
blkid | swap grep / dev / mapper / vgroot-lvswap: UUID = "12345678987654321" TYPE = Swap
Does the entry have to be?
vgroot-lvswap UID = 12345678987654321 / dev / urandom swap, offset = 1024, digit = aes-xts-plain64
