Subvolume created at /var/lib/machines without my permission

Hey guys,

I've recently discovered a subvolume in my btrfs file system but I have no clue of which package could have triggered the creation of this subvolume. The subvolume /var/lib/machines was created 4 days ago, in April 20th, together with a system upgrade.

# btrfs subvolume show /var/lib/machines 
/var/lib/machines
	Name: 			machines
	uuid: 			xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
	Parent uuid: 		-
	Creation time: 		2015-04-20 10:06:22
	Object ID: 		433
	Generation (Gen): 	47654
	Gen at creation: 	46248
	Parent: 		5
	Top Level: 		5
	Flags: 			-
	Snapshot(s):

And these were the packages I've updated that day.

And funny thing is that no package owns that folder/subvolume.

%  pacman -Qo /var/lib/machines 
error: No package owns /var/lib/machines

The only reference I could find was the man page of machinectl.
Can I safely delete this subvolume?

EDIT : typo

Re: Subvolume created at /var/lib/machines without my permission

Thank you. This gives me a satisfatory explanation. I won't delete it then.
