Thank you for the resources. However, I am stuck on running the run script from [2]. The only changes I made to the run script were related to the build options to fix some initial errors (I have attached the modified script below).

The error I get stuck on seems to be related to the ROM-Session, I have attached a log file below.

Best,
Rumen

There is indeed a port of the 'lwext4' [1] library for Genode and by now
a VFS plugin that utilizes the library. However, I recently moved it
from genode-world to my personal Genode “playground” [2].

[1] https://github.com/gkostka/lwext4
[2] https://codeberg.org/jws/genode-wundertuete/src/branch/sculpt-24.04-2024-04-19

I use it on a daily basis (it is integrated in my personal Sculpt branch
[3]) and at least in my limited usage it works well enough. There are
known limitations in the library (some features of Ext4 that are enabled
by default by now are not supported so you have to prepare the FS in a
certain way and sparse files are not supported) and the plugin itself is
quite plain.

So, since you aim for a “logging file system”, I assume your use-case
might require specific properties and given its current state, the
'vfs_lwext4' plugin probably does not fit the bill.

Josef
