Spectrum's root filesystem is immutable, so if you want to be able to
persist data between sessions, you'll need to create a persistent
storage partition. Spectrum comes with `cryptsetup`, and in future is
likely to assume that btrfs-specific features are available.
Persistent storage can be mounted as follows:
[source,shell]
----
cryptsetup open /dev/sda1 userdata
mount-userdata /dev/mapper/userdata
----
It's not mounted automatically, because generally the partition should
be encrypted, meaning a key has to be supplied to mount it anyway, and
because there might be multiple persistent data partitions to choose
from.
