Re: watchdog file change

You can use a "repair" script that just removes the file, sleeps a bit or better "sync"s the filesystem, then "exit 1". Watchdog reboots the machine when a repair script exits with a non-zero value. You may also see the case where the watchdog program thinks the file is too old because system time h...

Re: How can I turn wifi on after I used my Raspberry Pi 4 as a Access Point?

I suppose you need to comment the line in dhcpcd.conf that reads "nohook wpa-supplicant" for wlan0. Then restart dhcpcd.

Re: With overlay of root, swap does not work

FYI, I think there is now a new option in raspi-config to configure a rootfs overlay filesystem.

Re: RPi3+ only accepts every other connection attempt

Do not use 169.254.x.x, this network is reserved to ipv4ll (aka zeroconf, bonjour, avahi, APIPA). In addition to only working well when you don't meddle with it, this network is unroutable which is not practical. Create a regular network if you need, e.g. 192.168.1.0/24. Or continue using ipv4ll, le...

Re: External soundcard output just from one source

You need a software mixer. (With the built-in audio device, the mixer is included in the driver.) The kind of software mixer depends on the audio stack you're using. With Alsa alone you need a "dmix" device in your alsa configuration. See: https://wiki.gentoo.org/wiki/ALSA/en#Soundcard_only_availabl...

Mettre les Pi en DHCP à la place de la config statique. Configurer la box SFR pour leur donner les adresses souhaitées. C'est bon pour les cheveux.

Re: 1st boot and update takes very long

Yes it appears to take a long time... The OP says the update is running for one hour. Can it really be that long? I've seen slow updates on other Pis, but never one solid hour I think. Also the slow first boot probably means SD resizing took its sweet time. As if the Pi was having problems with the...

Re: Set password when provisioning

You'd need to modify the SD before it runs for the first time.
I suppose adding a script would be the most appropriate solution. In the spirit of the one that does one-time SD root partition resizing on Raspbian.

Your OS is running off the SD, or one of the drives?
