  • What is this about? I need to setup some key? Or ignore it? This is
    new 17.10 installation. Swap is on, file /swapfile exists. Home
    encryption enabled, at setup.

  • How about SSD installation, may be swap should be turned off? RAM is
    enougn. Anyway I don't want to crypt it, processor is too slow.

leonid@LeonidMew:~/Downloads$ sudo update-initramfs -u



update-initramfs: Generating /boot/initrd.img-4.13.0-32-generic
cryptsetup: WARNING: Invalid source device /swapfile
cryptsetup: WARNING: target cryptswap1 has a random key, skipped


Update: What means priority -1, is it turned off?



leonid@LeonidMew:~/Downloads$ swapon -s
Filename Type Size Used Priority
