⚡ Getting started

1. Run npx serve and go to http://localhost:3000
2. There is no step 2

🛠️ Update the filesystem

1. Run the build process in the buildroot package

2. Synchronize the new filesystem using:

./scripts/sync-fs.sh

3. Cold boot and save a new snapshot

❄️ Cold boot and saving a new snapshot

1. Go the http://localhost:3000?boot=true

2. Once the boot is completed, clear the cache and start psql (the runtime assumes psql is running when it loads a snapshot): echo 3 > /proc/sys/vm/drop_caches && echo 3 > /proc/sys/kernel/printk && reset && psql -U postgres

3. Save the state to a file clicking the Save state to file button

4. Put the state file into the state folder and compress it using zstd:

zstd --ultra -22 state/v86state.bin && rm state/v86state.bin

5. Go to http://localhost:3000, instant boot!
