A persistent object is an object that survives reboot.
On [[Unix]], files and directories are persistent but
processes and [[unix/file_descriptor]]s are not. [[microkernel/EROS]] is
an example of an orthogonally persistent system:
processes and [[capabilities|capability]] also survive reboot. To a
process, it generally only looks as if it had not been
scheduled for a long time; the rest of its environment
remains essentially the indistinguishable.
# GNU/Hurd
The GNU/Hurd is not a persistent system: there are no persistent
[[capabilities|capability]]. All data that is stored in files in the file
system, is serialized.
