When lzma is invoked, it often maxes out my 1500 MHz Athlon cpu and hangs the system. I can't even remaster the system, or download a big file, etc. because of this. Slitaz is a great system, but this problem greatly limits its usefulness for me.
Since we're sharing lzma problems. I have a livecd hard drive install of 3.0 , tazusb writefs lzma results in a rootfs.gz that errors out on boot. Never bothered to investigate since tazusb writefs gzip works
