# This file defines the "non-hardware dependent" part of opt-in persistence
|
||
|
|
# It imports impermanence, defines the basic persisted dirs, and ensures each
|
||
|
|
# users' home persist dir exists and has the right permissions
|
||
|
|
#
|
||
|
|
# It works even if / is tmpfs, btrfs snapshot, or even not ephemeral at all.
