Glitch in "Upgrading from EOL Fedora using yum"

[Philip A. Prindeville]

I was reading the document:

http://fedoraproject.org/wiki/Upgrading_from_EOL_Fedora_using_yum#Fedora_16_-.3E_Fedora_17

and got to the section:

	If you have /var on a separate partition, you will have to manually convert "/var/run" and "/var/lock" to a symbolic link.

	# mv -f /var/run /var/run.runmove~
	# ln -sfn ../run /var/run
	# mv -f /var/lock /var/lock.lockmove~
	# ln -sfn ../run/lock /var/lock

but when I tried this, I get:

	[root at mail /]# mv -f /var/run /var/run.runmove~

	mv: cannot move `/var/run' to `/var/run.runmove~': Device or resource busy
	[root at mail /]#

right off the bat. Anyone know what the workaround is for this?

Thanks,
