gokrazy VS rpi-clone

Switching to gokrazy[0] was the best thing I did for my Raspberry Pi uptimes. I think a lot of that is because it defaults to using read-only partitions so the common issue of SD cards falling over when you run apt upgrade no longer happens.

But I also think that gokrazy's simplicity and design helps it be just a solid, reliable foundation to build on top of.

The idea there sounds a lot like https://gokrazy.org/, which builds a minimal go userland, wrapping one or more user provided go applications, and bundles in a linux kernel.

Targets mostly at single board computers, and I think it downloads pre-built kernels (and bootloaters if needed), rather than trying to build them directly, since getting a working cross compilation toolchain set up and plumbed into the kernel compilation process is still a pain.

I've personally only used yocto/open-embedded for that which does nicely handle building the cross-compilation toolchain, kernel image, and modules. But it is kinda overkill for that task, being designed to build a whole userland too.

reminds me of https://github.com/gokrazy/gokrazy which does similar things.

https://gokrazy.org/ would like a word

Fun! We have support for running on gokrazy (https://gokrazy.org/) already, and that's probably where Unikernel Linux is more applicable for us, for when people just want a "Tailscale appliance" image.

I'll email you.

I've been running a bunch of Pi's for years now, and the biggest problem I've had is the Pi itself dying: 24/7 usage is hard on a small device. I've also found that stable power is essential, and to that end I've always used 5v 3a branded power cubes, plugged into a pure sine wave UPS. Choice of micro-SDHC cards is important and I ended up getting ATP industrial cards (https://www.atpinc.com/products/industrial-sd-cards) - expensive but really long-lived. Finally, using RPi-clone (https://github.com/billw2/rpi-clone) on a regular basis has been a life-saver. I clone to Sandisk Extreme micro-SDHCs and can recover from an outage in minutes.

I would normally use the Pi SD-Card copier to duplicate the SD-Card to an SSD but I'm unsure if this is available on the Ubuntu image - you could possibly use this program [Github] if you are not keen on using dd with a running system.

Then you will need to clone the SD to the SSD, you can use many tools that are available from your desktop computer or you can try with rpi-clone, just connect the SSD with Pi booted from SD, stop any possible service/docker to prevent any copy error and run, adapting device naming but usually will be (check device with dmesg):

I used rpi-clone, it was super easy. Whole process took 10 minutes. https://github.com/billw2/rpi-clone
