I am trying to create a swapfile on my fedora 35 system and do not know what I am doing wrong:

Why do you need to create a swapfile? Such details are normally handled by the installer in a way that works for
the majority of users. Is your F35 a fresh install or upgrade?
If I follow the swapfile instructions on
https://docs.fedoraproject.org/en-US/Fedora/14/html/Storage_Administration_Guide/s2-swap-creating-file.html
It is unwise to apply Fedora 14 documentation on Fedora 35 -- a lot has changed. Are you using the default brtfs
filesystem? On my F35 system with btrfs (and 16GB RAM):
% swapon -s
Filename Type Size Used Priority
/dev/zram0 partition 8388604 30208 100
I get the following result:
step 1:
trash>sudo dd if=/dev/zero of=/swapfile bs=1024 count=65536
65536+0 records in
65536+0 records out
67108864 bytes (67 MB, 64 MiB) copied, 0.147119 s, 456 MB/s
step 2:
trash>sudo mkswap /swapfile
mkswap: /swapfile: insecure permissions 0644, fix with: chmod 0600 /swapfile
Setting up swapspace version 1, size = 64 MiB (67104768 bytes)
no label, UUID=f1402a6a-c64c-4f84-9d47-4f8822d2f1d2
step 3:
sudo chmod 0600 /swapfile
step 4:
trash>sudo swapon /swapfile
swapon: /swapfile: swapon failed: Invalid argument
