ORAS and bootable containers - downloading images from registry about lima HOT 3 OPEN

Using mounts needs a special image (with sshfs), since 9p has been disabled in the kernel.

One also needs to make sure to use an image with cloud-init included, and with ssh enabled

dnf install -y openssh-server cloud-init sshfs

As a workaround, it is possible to add the fuse-sshfspackage and reboot

Note, as a special case Fedora CoreOS (and similar) make /usr/local writable with a symlink:

lrwxrwxrwx. 3 root root 15 Jan 31 13:55 /usr/local -> ../var/usrlocal

This enables the regular containerd (nerdctl-full) installation to work, even if /usr is read-only...

Alternatively, one could change the guestInstallPrefix to something else (and convince systemd)

lrwxrwxrwx.   3 root root    8 Jan 31 13:55 home -> var/home
lrwxrwxrwx.   3 root root    7 Jan 31 13:55 mnt -> var/mnt
lrwxrwxrwx.   3 root root    7 Jan 31 13:55 opt -> var/opt
lrwxrwxrwx.   3 root root   12 Jan 31 13:55 root -> var/roothome

The biggest downside is the enormous size and the hard-to-use, so in that sense it's like CoreOS et al...

But one can use ORAS for the storage, without switching over to the rest of the "bootable containers"?

Another related topic would be to support IPFS for storing images, and download them with ipfs get
