Dev still said host agent 0.2.13 and desktop 0.1.0, while prod serves
0.2.16 and 0.1.2. The next dev→prod merge would have sent new installs
back three host releases. This brings dev to prod's numbers. No other
change: the rest of this branch is already on dev.
/download/windows and /download/linux redirect to a one-minute signed URL
for the current desktop app, from the same private bucket as the host
agent, so a download page can link to them once and every download still
passes through the API. Which version they hand out is a constant bumped
by a commit after a release is published, as the host installer's is.
/desktop.sh installs it on Linux for the calling user: one binary in
~/.local/bin and a launcher entry, no root.
- **Installer:** piped into `sudo`, installs to `/usr/local/bin`, and
hands onboarding `/var/lib/nestri`. Root lets the host agent jail each
box under its own uid and give guests a network. A host that ran the
agent as the sudo user has that state copied over (never moved), so it
keeps its machine identity and its downloads. Pins host agent 0.2.4.
- **Base image:** `vhost-user-nvgpu` and `nvgpu-userspace`, static
(musl), from the same `NVGPU_REF` as the guest driver and Vulkan layer,
under `/boot/host`. The host agent takes them out at unpack, as it does
the kernel, and forwards the GPU when it finds the NVIDIA driver loaded.
Merge after the host agent 0.2.4 release: the installer pins it.
GET /install.sh serves a POSIX script, embedded in the API at build time
so the script and the routes that redeem its token ship together. It
checks the platform, asks where box images should live, downloads the
host agent at a pinned version, verifies it against SHA256SUMS, installs
it for the calling user and hands over with the token in the environment
rather than argv.
GET /install/:component/:version/:asset redirects to a one-minute signed
URL on a private S3-compatible bucket, so every download passes through a
route that can be logged or switched off. The SigV4 signer is written
against Web Crypto and checked against AWS's published example.
