Configuring image for emmc (CM4)

[jctullos]

Hi!

Thanks for writing this program! It's been extremely helpful creating new images to flash for our customers.

I took a running CM4 that has an older codebase on it that's operational, our customer was having some issues with a later upgrade to the CM5, and they lost the original software that's running great on the CM4. So I extracted the rootfs and bootfs from the running software, and now flashing that to a new CM4.

But I'm having issues with how to correctly set everything up so that the PARTUUID and any other unique ID gets replaced correctly for the new CM4. When it boots up, it can't find the root partition and fails to boot up.

Here's the command I'm using:
sudo sdm --hostname msrs 2024-10-22-raspios-bookworm-arm64-lite.img
--poptions noupdate,noupgrade,noautoremove
--customize $1
--logwidth 132
--extend --xmb 32768
--nowait-timesync
--plugin @./my.plugins
--regen-ssh-host-keys

My plugins file:
user:deluser=pi
user:adduser=pi|password=climbing
raspiconfig:net_names=1|boot_splash=1|i2c=1
disables:piwiz
L10n:keymap=us|locale=en_US.UTF-8|timezone=America/Los_Angeles
network:netman=network-manager|noipv6|timesyncwait=30
hotspot:device=wlan0|hsname=hs|hsenable=y|type=routed|dhcpmode=nm|wifissid=CM4|wifipassword=changeme

All of the mucking with PARTUUID happens when you burn the disk, so you haven't given me anything to work with here. And, I have exactly 0 experience with a CM4/CM5 so don't understand how one of them is burned.

Happy to help you, but I'm going to need more info. If there's info that you'd prefer to not post publicly, email me (address in the README).

Ah! Got it. Yeah, I'll email you and I'll also update this issue after with the answer for others to use if they need it!
