Most unikernels dont have the notion of users, groups, or multiple processes on purpose for security and performance reasons.
Some unikernels use the best in class file systems available like zfs by default.
Containers have all of these. Containers aren't unikernels.
Drivers are way less of a concern cause all you need is a clock, a network driver and a disk driver, not 30 different USB drivers, half a dozen networking drivers and more. Half of linux is just drivers cause it's designed to run on real machines whereas unikernels are explicitly designed to run as vms.
Happy to engage with real life examples on these concerns but the best way to truly understand since there's all sorts of misunderstanding here is to just simply deploy one.
