The size of `/var/vcap/data` is configurable and large, where as the `/` root volume is fixed and small.

**We want to use `/var/vcap/data` for storing everything that is ephemeral, `/var/vcap/store` for everything that is permanent, and avoid the root volume.**
!!! tip
BOSH design expects that `/var/vcap/data` is used to store ephemeral data, while `/var/vcap/store` should contain permanent data. Writing data to the root volume is strongly discouraged.

For example, we want to use `/var/vcap/data` to install software packages, job templates, and log files. Except I've previously indicated that the filesystem location for these three was `/var/vcap/packages`, `/var/vcap/jobs`, and `/var/vcap/sys/log`.
