It seems the whole thing's going into a direction where a whole own subtopic is coming up: compressed built-in filesystem. Haven't had a deeper thought about it yet, whether or not existing filesystems like squashfs, initramfs, etc are the right thing for that, or something new should be invented, but a generic mechanism for compiled-in compressed (ro) filesystems could also be interesting for very small devices, that perhaps even dont need any persistence. Some requirements coming up in mind: 1. it shall be possible to have any number of instances - possibly by separate modules. 2. it shall be possible to use an bootloader/firmware provided image (so it can serve as initrd) 2. data should stay compressed as long as possible, but uncompressed data might be cached - do decompression on-demand 3. only needs to be ro (write access could be done via unionfs+friends) 4. it shall be swappable (if swap is enabled) In that scenario, these in-kernel headers would just one consumer, I can imagine lots of others. --mtx -- Enrico Weigelt, metux IT consult Free software and Linux embedded engineering info@xxxxxxxxx -- +49-151-27565287
