I think there is a kernel parameter you need to change as well.
Not in my experience. /boot/cmdline.txt and /etc/fstab on the new partition is all I've ever had to change.
Thanks, that worked spot on. Soon as I altered stab it worked fine.

Re: Change root in cmdline.txt

Now obviously I've done something wrong then. I copied the actual ext4 partition (not just files within, used gparted to copy partition) to an external drive, got the PARTUUID then checked ID same when plugged in the the Pi. Then deleted the ext4 partition on the SD card having altered the location ...

Change root in cmdline.txt

Folks, Think I misunderstood something some time back that I read in an article somewhere. In the cmdline.txt file in the /boot directory there is an entry as follows; root=PARTUUID=c82337fe-02 which seems to allow setting the root directory to a different location. Now I am thinking you need the op...

Servers Power Consumption

Curious folks, If a server is installed is it consuming any power when idle or is it mainly just when serving services? I'm guessing when idle power consumption is probably extremely low but increases under load. Reason for enquiry is basically CPU temperature, seems very important with Pi4 and am w...

Lede / Openwrt can also be installed on a RPi to turn it into a router. It's available for many devices. (also installable via PINN ;) )
Now the Pi 4 is out with gigabit ethernet this becomes a decent option.

Re: Temporary Router

I'd rather suggest adding a bridge (possibly anonymous = sans IP address), in other words turn the Pi into a 2-port ethernet switch, that will see all the traffic pass through it without changing anything to the network setup. Great suggestion but for my minimal requirements might be too much. Thin...

WiFi Repeater Security

Folks,

Last year there was a bit of a scare with wifi security and although no evidence of hack taking place manufacturers were busy putting out security updates.

At the time, and I'm not sure why, repeaters were considered vulnerable.

Does anyone know if this is still the case?

Thank you for prompt reply.

I have five Pi devices running projects but seldom had a need to use GPIOs other than I use UART to USB (Think that is what it is called) to actually set the Pi MicroSD card up.

The popular KY-019 5V relays used with Arduinos, appreciate they are 5V, can the R-Pi GPIO pins control this relay?

I think the 5V output GPIO pin is OK to power it, I am wondering about the signal to the relay which is 3.3V on the Pi.
