Hi,

/usr/lib/systemd/system/NetworkManager.service contains:

ProtectHome=read-only


See `man systemd.exec`. You may change that via

  $ systemctl edit NetworkManager.service

but a better idea would be to choose a directory like
/var/lib/NetworkManager, which is required to be read-write and
persisted. Also, because NetworkManager is a system daemon and has no
business with your home directory.


best,
Thomas
