Ubuntu Customization Kit

unsquashfs instead of "cp -a"

Asked by Andrea Gelmini

Hi all,
   this little stupid patch force the use of /usr/bin/unsquashfs, instead of "cp -a", to unpack rootfs. it's a lot faster, of course. less seek, linear decompression, and so on. Do you think is it right to include in next release?

Thanks a lot for your work and time,
Gelma

this sounds really interesting, I tried that some time ago but unsquashfs did not support squashfs 3 or something like that. on what ubuntu release did you try that?

Hi Fabrizio,
   it works with squashfs-tools_3.2r2-2build1_i386.deb, the one in Ubuntu 7.10.

Thanks for your time,
Gelma
