Antergos does not seem to activate a swap partition through an entry in /etc/fstab. I have a swap partition, and swap is active
# free total used free shared buff/cache available Mem: 16299680 3022996 10148948 878504 3127736 12441736 Swap: 15624188 0 15624188
Yet, to my surprise, I do not find an entry in /etc/fstab
cat /etc/fstab # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> # UUID=88be1980-ce4e-47df-ac60-dbb23fcbda7a /home ext4 defaults,noatime,data=ordered 0 0 UUID=640D-6FFF /boot/efi vfat defaults,noatime 0 0 UUID=b6b343f5-6c13-43a3-9c06-8c6b8502339d / ext4 defaults,noatime,data=ordered 0 1
How is Antergos handling this? How is Antergos activating swap since it is not done through /etc/fstab? I learned that swap can be handled through systemd (https://wiki.archlinux.org/index.php/swap), but systemd-swap is not installed on my Antergos system. So it must be another way.
Reason I am asking: I want to convert my swap partition to a smaller swap file (as i am on SSD with plenty of RAM), but I would want to disable the current swap partition in a correct way before removing the partition.
