Subject: [PATCH] Implement read-only mode for ssids
|
|
|
|
With this change it's possible to define `network=`-sections in a second
|
|
config file specified via `-I` without having changes written to
|
|
`/etc/wpa_supplicant.conf`.
|
|
|
|
This is helpful on e.g. NixOS to allow both declarative (i.e. read-only)
|
|
and imperative (i.e. mutable) networks.
