| # Live_usb |
| |
| This component can be included in a build to support writing a sparse FVM to a |
| a ramdisk during boot, which results in a temporary FVM which is lost once the |
| system is rebooted. |
| |
| This enables trying Fuchsia without worrying about paving a device or |
| sacrificing a computer to try it on. |
| |
| ## Using it |
| |
| 1. Set up a Fuchsia development environment. |
| 2. Run the following in a shell: |
| |
| ``` |
| $ echo 'boot.usb=true bootloader.default=local devmgr.bind-eager=usb_composite' > cmdline |
| $ fx set workstation_eng.x64 && fx build |
| ``` |
| |
| 3. Insert a USB device. We will call it `/dev/sdX` - replace X with the |
| appropriate drive letter. |
| 4. Run the following: |
| ``` |
| $ fx make-fuchsia-vol --use-sparse-fvm --cmdline cmdline /dev/sdX |
| ``` |
| 5. Insert the USB drive into a Fuchsia-compatible computer, boot from it, and wait a minute or two. |
