The cloud-image install flow is gone; reword the last comments that still
referenced it:
- asb_core.c: "Linux cloud-image creates" -> "Linux ISO creates"
- disk_util.c: drop the "Ubuntu cloud-image parent ~2.5 GB" rationale
from vhdx_create_differencing_resized (now describes the generic
inherit-then-resize behavior)
- disk_util.h: stage_linux_agent_and_extras doc no longer says "same
content the cidata builder used to ship"
- appsandbox-agent.c: "autoinstall lets the user pick" -> "the create-VM
modal lets the user pick"
App Sandbox Linux guest daemons
In-VM Linux daemons that speak the same vsock wire protocol the Windows
App Sandbox host expects. See docs/linux-idd-implementation-plan.md in
the repo root for full architecture and wire-protocol reference.
Daemons (this directory)
| Binary | Channel | Listens on | Privilege | Status |
|---|---|---|---|---|
appsandbox-agent |
control | vsock :1 | root (system) | implemented |
appsandbox-input |
input | vsock :3 | root (system) | planned |
appsandbox-display |
frames + cursor | vsock :2 | root (system) | planned |
appsandbox-clipboard |
clipboard | vsock :5, :6 | user (user unit) | planned |
Build (inside the VM)
sudo apt-get install -y build-essential
make
Install + enable (inside the VM)
sudo make enable
This installs to /usr/local/bin/, drops the systemd unit into
/etc/systemd/system/, runs daemon-reload, then
systemctl enable --now appsandbox-agent.service.
Smoke test
systemctl status appsandbox-agent
journalctl -u appsandbox-agent -f
You should see listening on AF_VSOCK port 1. Once the host-side Phase 1
service-GUID switch lands, the App Sandbox UI's agent dot will turn green
within a few seconds of the unit being active.
Uninstall
sudo make disable
sudo rm /usr/local/bin/appsandbox-agent /etc/systemd/system/appsandbox-agent.service
sudo systemctl daemon-reload
