Squashfs LZMA support

written by Tomas M. 2 years ago

In the last few days, Phillip Lougher (squashfs author) published several patches, which is a very important step towards the new lzma support. In short, the patches move the decompressing functions to a separated file, and replace the zlib_uncompress() call by squashfs_decompress(). This is exactly what had to happen in order to provide a decompressor framework for Squashfs, 'allowing multiple decompressors to be easily supported'.

Since it (lzma) is already in kernel for some time, I think that we should see LZMA support in squashfs very soon.

Sorry for asking (I'm a noob), but wha does this mean for Slax? Will it be easier to use the live scripts?

[2] Ivo Georgiev wrote 2 years ago:

He will soon move to the new SquashFS, so things will get updated. You will notice this - the modules format will be different.

"the modules format will be different."
What? Again? :(

[4] Tomas M wrote 2 years ago:

Yes, again, for the last time, I hope. There is an advantage - you will be able to mount the modules on all Linux distros with recent kernel. The format will be official and widely supported.

And yes, it will be much easier to use Linux Live scripts, because you will not need to patch squashfs and lzma into it. You'll only get a recent kernel version (you'll be even able to use your native Linux Kernel from your distro) and you'll just compile aufs fot it (unfortunatelly aufs doesn't seem to be merged to kernel mainline yet, not due to the code but due to the lack of interest from kernel developers).
