When -d option is used with swapon, is expected that there is an equal
'=' which at least according to the man page it doesn't make sense or
it's not properly explained.
If we use -d as we should, then swapon takes 'once' or 'pages' as an
actual device:
dhcp33:~ # swapon -p -2 -d once /dev/sdb1
swapon: stat failed once: No such file or directory
The short option -d, should be something like "swapon -d once ...." not
"swapon -d=once ...."
I've attached the patch to fix this small issue.
