squashfs-lzma “linux-live-script”
TraperJohn:
All right so how do we build one for TC 2.x?
Jason W:
Squashfs-lzma is not supported for squashfs 4.0, but when lzma makes it into the kernel there may be patches made for it:
http://www.nabble.com/squashfs-4.0-lzma-support-td22269948.html
Squashfs 4.0 is the version in the kernel and the one used by TC. A squashfs-lzma 3.4 module could be built, but that would preclude the use of regular squashfs-4.0 tcz's, which is now a supported extension format, once that module is loaded. So it would be better not to have a squashfs-lzma extension in the download area.
Of course, even when or if lzma makes it into the mainline kernel gzip will still be the compression method preferred by TC.
TraperJohn:
Any other high compression algorithms that will work with squashfs 4.0 in a simullar fashen to lzma with 7z like results?
jpeters:
Interesting comparison study
http://odzangba.wordpress.com/2009/03/25/gzip-vs-bzip2-vs-lzma/
My vote is for speed, although bzip2 seems like a good compromise. lzma is in a league all it's own for
slowness.
TraperJohn:
http://odzangba.wordpress.com/2009/03/25/gzip-vs-bzip2-vs-lzma/ is right but We wouldn't need to compress applications more then once as we only are mounting them with activate.
O and by the way in my own mount tests with zip to lzma I see only a small diff about 3-4 seconds on my last gen P4 system.
I found some 7zip compression algorithms written to work with gzip on sourceforge.net but 0 that exist in the kernel.
I'm not sure as to how to search this one out.
Any one know what to look for?
