The way you configured `vfs_block`, it imports the content of the ROM in to the RAM and allows to modify it, but the changes can't be written back.
How can I make the block changes persist between runs? In previous versions of Genode I could achieve this with lx_block, but I am unsure how to do this with vfs_block.
I would try something as follows:
```xml <requires> <file_system label="lx_block"/> </requires>
....
<start name="vfs_block" ram="1G"> <provides><service name="Block"/></provides> <config> <vfs> <fs label="lx_block"/> </vfs> <policy label_prefix="vfs" file="/snapper_block.raw" block_size="512" writeable="yes"/>
</config> </start> ```
then remove the `<rom label="snapper_block.raw"/>` from `<content>`.
This should start an `lx_fs` component in the runtime. Which if I remember correctly will serve the content of the sub directory `lx_block`. Your needs to be in that sub-directory.
I write this from the top of my head without actually trying it out, so there might be some steps I missed.
