After FreeBSD is installed a secondary filesystem will be created,
mounted on /users, to hold the home directories of researchers that
are conducting experiments on your node. This secondary filesystem
will use the remaining space on your boot disk; on an 8GB disk, there
is typically 2GB left after installing FreeBSD. We also reserve an

Linux is not supported at this time. However, the required support is
minor (just some some config files and scripts) and we plan to add
that very soon. Please stay tuned for further information.
