Ramdisk already defined
I am trying to mount the ramdisk for sorting, and i get the message "ramdisk already defined." What exactly is /dev/ramdisk0 and is it safe to remove it?

# command
sudo -S mktd 60 <<EOF
initiate
EOF

# block of code for mktd
...
[ -e /dev/ramdisk0 ] && {
print "ramdisk already defined."
exit -1
}
...

Thanks,

- CB

This is an OS-specific issue. Are you using Linux? If so, what is "mktd"? If not, which OS? If you are trying to mount it, why would you create the device node?
