Does anyone reuse /boot or /var partitions ?

I reuse tons of sub-directory of /var

	/var/lib/mysql
	/var/lib/libvirt/images
	/var/cache/mock
	/var/lib/mock

Ok, I don't really need them on install
(I usually re-enable them after install)

Yes, I use shared /boot for multi-boot (multiple fedora version).

I don't think disallowint mounting an existing partition without
reformatting it is a good idea.
