the above commands.
|
||||
|
||||
`get_services()` and `manage_service()` come from napalm-device-types'
|
||||
`SystemdServicesMixin`; this driver supplies only the transport. An action runs as
|
||||
`timeout 45 systemctl --no-ask-password <action> -- <unit>.service`, so a unit that hangs
|
||||
on its way up or down cannot hold the session, and only the exit status decides whether it
|
||||
succeeded. Without a sudo password it uses `sudo -n`, which fails at once instead of
|
||||
waiting for a password prompt.
|
||||
|
||||
On OpenMediaVault (napalm-openmediavault inherits this driver), enabling or disabling a
|
||||
unit that OMV manages itself — Samba, NFS, SSH — may be reverted the next time OMV applies
|
||||
its configuration.
