Uh? Juniper sells those boxes without flash?

If running on flash, it mounts harddisk partitions as /altroot and
/altconfig and copies the flash content into those.

Because otherwise there is not too much sense in snapshots. For configs
you have rollback, for software jinstall/jbundle.

Snapshots are primarily a tool to protect you from media failure.
And given what I've seen happened to some few-years old M5/M10 REs,
it's a very good reason.

Probably not.
