libfstools: mount f2fs overlay with zstd compression

2026-05-23T15:44:55Z

When fstools_overlay_compression_type is set to zstd, pass the f2fs compress_algorithm=zstd:3 mount option while mounting the overlay. Retry the f2fs overlay mount without compression if the compressed mount fails, so existing overlays without compression support can still boot. This pairs the runtime mount behavior with the mkfs.f2fs compression feature bits enabled during overlay formatting. Signed-off-by: Robert Marko

libfstools: enable f2fs overlay compression formatting

2026-05-23T15:44:55Z

When fstools_overlay_compression_type is provided, format f2fs overlays with the extra_attr and compression feature bits enabled so the filesystem can later be mounted with compression options. Log when f2fs overlay compression formatting is enabled to make the selected path visible during first boot formatting. Signed-off-by: Robert Marko

mount_root: add kernel parameter to specify the overlay fileystem type

2026-03-17T16:16:16Z

The kernel parameter 'fstools_overlay_fstype' can now be used to specify the preferred overlay fileystem type. The supported values are 'ext4', 'f2fs' and 'auto'. Type 'auto' is the default and represents the usual behavior of selecting the filesystem type based on available space. Signed-off-by: Rodrigo Balerdi

mount_root: add kernel parameter to specify the overlay storage name

2026-03-17T16:16:16Z

The kernel parameter 'fstools_overlay_name' can now be used to specify the overlay backing storage by name. The name is resolved by the regular stack of fstools drivers. Signed-off-by: Rodrigo Balerdi

libfstools: Rename PATH_MAX to MTD_PATH_MAX

2026-02-15T18:20:01Z

The PATH_MAX defined here could conflict with PATH_MAX in include/limits.h. The definition in snapshot.h is not used. Just remove the definition from snapshot.h, because it is not used and rename the other definition. Signed-off-by: Hauke Mehrtens

libfstools: add support for EroFS based images

2025-07-05T13:17:57Z

Add support to libfstools to parse and support EroFS based images to permit correct mounting of OverlayFS with it. (in addition to SquashFS support) While at it rework the code to better handle the 2 different filesystem introducing a similar pattern.
