debian_guest package provides a basic Linux environment based on the Debian Linux distribution.
These steps will walk through building a package with the root filesystem bundled as a package resource. The root filesystem will appear writable but all writes are volatile and will disappear when the guest shuts down.

To boot on an ARM64 device, replace
guest launch debian
The Debian system exposes a simple telnet interface over vsock port 23. You can use the
guest CLI to connect to this socket to open a shell. First we need to identify the environment ID and the guest context ID (CID) to use:
$ guest list env:0 debian guest:3 debian
The above indicates the debian guest is CID 3 in environment 0. Open a shell with:
$ guest socat 0 3 23
All of the images constructed by
build-image.sh (see above) are available on CIPD. To update and upload those images run the following. The scripts will prompt for a CIPD auth token and for sudo access.
$ cd $FUCHSIA_DIR $ ./src/virtualization/packages/debian_guest/mkcipd.sh x64 $ ./src/virtualization/packages/debian_guest/mkcipd.sh arm64
