# This script reads user@host lines from ~/.server_hosts. Each host
|

|
|
# is a RHEL-like operating system where the dnf-utils and
|
||
|
|
# dnf-automatic packages are installed. dnf-automatic is configured
|
||
|
|
# to download and apply updates periodically. The 'needs-restarting'
|
||
|
|
# command provided by the dnf-utils packages is assumed to be
|
||
|
|
# available on each host. Each host is checked via SSH to see if it
|
||
|
|
# needs-restarting after core libraries and services have been
|
||
|
|
# updated since the last boot-up. If a restart has been initiated for
|
||
|
|
# a given host, notify-send will notify the user.
