* volume_id: volume_id_get_buffer with small FSesAlyssa Ross via busybox2026-02-041-3/+2
| | | | | | | | | | | | | | | I was working with some very small ext4 filesystems, used for overlaying on immutable VM/container images. If it's only desired to overlay a single config file, these filesystems can be very small indeed, and so ran afoul of this length check. Since 4fc5ec56f ("device matching against UUIDs: do not try floppies") (from 2009), floppy drives are skipped before this function is even called. Reading from an unused loop device returns 0, so it should be fine to reduce the minimum length.

* volume_id: add LittleFS detectionSven-Göran Bergh2018-01-193-0/+67
| | | | | | | | | | | | | | | | | | | | | Add support for LittleFS to blkid. Not included if FEATURE_BLKID_TYPE is not selected (neither UUID nor label). LittleFS is a small fail-safe filesystem designed for embedded systems. It has strong copy-on-write guarantees and storage on disk is always kept in a valid state. It also provides a form of dynamic wear levelling for systems that can not fit a full flash translation layer. (https://github.com/geky/littlefs) ARM has introduced it in its Mbed OS 5.7, so it starts to gain focus.
