The final tail of the file reading was incorrect, so our hashing was
"correct" but it was using stale data from the previous block size read.
Noticed this while wiring up the CI rootfs fetching since the hashing is
a lot simpler there.
Now instead of reading a tail, just attempt to read the full block size
and use the resulting data size instead. Confirmed it matches expected
results now.
In the process we are going to need to update hyperlinks and hashes
anyway, change the hash to XXH3 so it is faster to run.
This is definitely a bit divisive but overall this is a win.
This is a user pattern that is emerging in a bunch of projects.
Allow an officially sourced script that lets you pipe a script directly
in to python/bash and setup the environment entirely.
This only supports Ubuntu {20.04, 21.04, 21.10, 22.04} which matches
exactly what we expose in the PPA.
Once this is in the repo, and our PPA is updated to the latest release
tag you can run this script like:
`curl --silent <Direct Github raw link> | python3`
Once the PPA is updated, the README and Wiki will be updated with Quick
Start guides to use this path.
The script steps
1) Checks if ARMv8, or fail
2) Checks if supported Ubuntu, or fail
3) Checks if PPA installed
3a) Install PPA if not, or fail
4) Check if packages are installed
4a) Install non-installed packages, or fail
5) Check if RootFS is configured/exists
5a) Run through FEXRootFSFetcher to get/setup rootfs, or fail
6) Attempt to run emulated uname -a through FEX, or fail
7) Provide some examples for how to use FEX
8) Exit with success!
