Hi All,

I have a fedora 30 bootable flash drive.  /dev/sda5 is my "Linux
Swap".  To zero out my swap space to make it more friendly
with gzip?

I would try just dd'ing /dev/zero across it, but I am afraid I
might break some file structure or some other stuff.

Many thanks,

I found this:

   # swapoff -a
   # swapon -a

But does it zero out the bits?
