In the last couple of days, $SUBJ has hit me twice, so I had to wonder if I could somehow prevent it?
Hardware is a Nano Pi Neo Air, access is via ssh.
first I patched a 15.2 Leap system, and when wpa_supplicant was updated, output over ssh just stops, although the process continues on the ARM board. (verified via a serial console).
just now, I was running a zypper dup from 15.1 to 15.2, and the same thing happens. wpa_supplicant is installed, network is interrupted.
Which network management system are you using? Maybe it's worth trying a # systemctl daemon-reload # systemctl restart network[ing] but quite how you would automate that if it works is beyond my pay grade. I suppose a frequently run cronjob could run a script that checked for wlan down and restarted it if necessary? But maybe there's a systemd incantation?
Over the serial console, I can tell the wlan interface is down, which explains what happens.
I don't always have the luxury of having a serial console attached, so updating could leave me with no access to the ARM board. I need to fix a few things after the zypper dup, so I need to retain the network access - any suggestions?
