- PERPOS (from Computer Consoles, Inc.; ran on the Tahoe amoung other
- machines), did. Nested transactions in fact. You specified which
- filesystems were to have an atomic protocol active. Part of the
- system also recovered from failure to your TERMINAL so partial
- transactions could be recovered from a different terminal (terminals
- had to be routed through a separate terminal server from the cpu for
- this feature to be active).
-
- PERPOS was intended to be a high-availability operating system for
- multiple partially redundant cpus and disks originally developed for
- telephony contracts...
