I have two routers, ADM5120-based Edimax and LinkSys WRT54G v5,

slower than 300Mhz. I look askance at anyone who wants to make an

100% agreed. I love squashfs because it's tiny and efficient, and I
would not want to see it getting heavy.
Thanks! I'm determined to keep Squashfs as small/efficient as
possible, as that's where I see its main advantages.
BTW, has someone tried to port LZMA to squashfs ? I tried so on
bzImage + initramfs, and got something like a 27% smaller image.
That would mean about 500 kB on a 2 MB image.
There are quite a few third-party LZMA patches for Squashfs. OpenWRT
(for wifi routers) uses an LZMA patched Squashfs.
I've been asked about using LZMA for Squashfs quite a few times.
The major problem as I see it with LZMA is it is not supported by
the Linux kernel, and I don't want to use anything that might prevent
it being merged! At the moment I'm happy with the current situation
where there's third party patches available for those that want or
need it. Of course if the situation changed with LZMA going into the
Linux kernel, then I'd see no problem in using it in Squashfs.
