bootc install-to-disk seems to "reset" any passwords.

[cdrage]

When installing via bootc install-to-disk with these commands:

sudo podman run \
--rm \
--privileged \
--pid=host \
-v /var/lib/containers:/var/lib/containers \
-v /dev:/dev \
--security-opt label=type:unconfined_t \
mycontainer/foobar \
bootc install to-disk /dev/nvme0n1 --filesystem xfs --wipe

With a "test" Containerfile:

FROM quay.io/fedora/fedora-bootc:43
# ONLY FOR TESTING bootc install-to-disk
RUN echo "root:root" | chpasswd

After installing to disk, unplugging the live USB stick and booting into the OS, I'm unable to login as root/root.

To replicate:

1. Build your Containerfile above ^^
2. Perform the bootc install-to-disk to a bare metal / actual device
3. Try to login (wrong password).

I can confirm that:

• I do NOT run into this issue if I create the .raw from bootc-image-builder / I am able to login fine.
• Building the "anaconda-iso" and using that, I will also not get this issue either.

There could be a bug here for sure but philosophically/technically we shouldn't be mutating the OS/container content in general all in to-disk.

I think what's actually much more likely going on here is that bootc-image-builder and Anaconda are mutating target image state by default; both have mechanisms to mutate root passwords and accounts, but to-disk doesn't.
