lzma

just another useless question.

slitaz 3.0 - rootfs w/lzma compression generally make the kernel panic while decompressing. using gzip is ok. someone explained why once, don't remember exactly where. but someone else could he explain to me why basic isos, stable/cooking, contain an lzma-compressed rootfs that the same kernel can load ?

Re: lzma

When an iso is made with tazlito the root file system is compressed one time.

The panic occurs after numerous tazusb writefs lzma

Re: lzma

thank you. but what is the difference between my filesystem, uncompressed from lzma rootfs, and the "original" filesystem, that could prevents lzma compressing + uncompressing ?

is there a special way to store the filesystem, files to remove, or anything ?

as i have to create rootfs from several linux distros, i don't use tazusb or tazlito to compress my rootfs. is there a different way to use cpio/lzma ?

Re: lzma

Also LZMA2 is better than LZMA, if you compress already compressed data.  LZMA2 is faster for 4-threads, if you compress big file (more than 256 MB), so 7-Zip will be able to split it to blocks. More about LZMA and 7zip.....
