Here is how I set the swap:
sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1MB count="1000"
sudo /sbin/mkswap /var/swap.1
sudo /sbin/swapon /var/swap.1
Every time I reboot/restart the swap is gone.
The command free
gives me zeros for swap. But the file /var/swap.1
is still there.
swap.1
file details:
-rw-r--r-- 1 root root 989000000 Aug 9 20:55 swap.1
The number 989000000 seems a bit big...
How can I make it persistent?

- Why do you think that? It seems a bit small to me given the commands you posted should be creating a file that is 1000*1MB (1048576000 bytes).10^6
not the2**20
I was expecting. Stupid SI vs binary prefixes.
