It is possible to boot from usb by default, without an sd card. I already made an os image on the ssd, and started experimenting with it. For now, it's been online for a whole night, and everything seems to be fine.Can't remember if the zero2w has boot from USB enabled by default. It might not as on the 3A+ (same base SoC in different packaging)enabling it permanently prevents the Pi being used as a USB device (a.k.a gadget mode).
That's a great idea! I haven't thought about this before, but I'll definitely give it a shot if I decide to buy an sd card later on. Thank you for your suggestions!An alternative to booting from USB (or a combination of USB and SD) is to stick with SD card and enable teh read onlt root filesystem overlay. The downside with that is that all changes live in RAM (which the zero2W doesn't have much of) and are lost when power is removed or the system is rebooted. The plus side is that no writes occur to the SD card. No writes = no wear on the SD card and no chance of corruption on an unsafe shutdown.
