[one-users] [VMware ESXi] What's the purpose of exporting var/ ?

[benpro]

Hi,

like my subject said, what is the purpose of exporting var/ via a NFS
share ? I don't get it.

Actually I use this scheme :

ONE_LOCATION=/srv/cloud/one
My images (instances of the VMs) is in /srv/cloud/one/var/images,
which is a NFS mount.

So why I need to export the var/ ? ESXi have the datastore which is
the same NFS mount as /srv/cloud/one/var/images.
If you can give me some information, because for me this is unnecessary.

In advance, thanks.
