- `xfsprogs` was updated to version 6.18.0, which enables parent pointers and exchange-range by default. Upstream recommends not to use these features with kernels older than 6.18.
GRUB2 is likely unable to boot from filesystems with these features enabled.
- `services.xtreemfs` has been removed as the `xtreemfs` package was broken and unmaintained upstream.
- `lunarvim` package has been removed, as it was abandoned upstream and relied on an old version of `neovim` to work properly.
- `opengfw` package and `services.opengfw` module have been removed as the upstream GitHub repository and website have been shut down.

The sync mode influences how operations are committed to the disk
log before the operation is acknowledged to the caller.
-ASYNC mode the writes to the disk log are buffered in memory by the operating system. This is the fastest mode but will lead to data loss in case of a crash, kernel panic or power failure.
-SYNC_WRITE_METADATA opens the file with O_SYNC, the system will not buffer any writes. The operation will be acknowledged when data has been safely written to disk. This mode is slow but offers maximum data safety. However, BabuDB cannot influence the disk drive caches, this depends on the OS and hard disk model.
-SYNC_WRITE similar to SYNC_WRITE_METADATA but opens file with O_DSYNC which means that only the data is commit to disk. This can lead to some data loss depending on the implementation of the underlying file system. Linux does not implement this mode.
-FDATASYNC is similar to SYNC_WRITE but opens the file in asynchronous mode and calls fdatasync() after writing the data to disk.
-FSYNC is similar to SYNC_WRITE_METADATA but opens the file in asynchronous mode and calls fsync() after writing the data to disk.
For best throughput use ASYNC, for maximum data safety use FSYNC.
