## Usage
Just download and run.
Just run the script, and follow the instructions.
## Known issues
`menhera.sh` will try to download a new rootfs into the memory, replace the old rootfs and kill all processes reading the old rootfs. The old rootfs will be mounted to `/mnt/oldroot`. An example filesystem structure after running `menhera.sh` on my test VPS:
* Cannot auto detect rootfs URL
```
root@localhost:~# findmnt
