[Buildroot] [PATCH 0/2] use host compressor for rootfs

[Philippe Reynes]

Hi Baruch,

I've missed this "mandatory dependancy".
I suppose that this dependancy is usefull to uncompress tarball.
But I think that the compilation of firmware should be done with
tools compiled by buildroot.

If lzma is used to compress the rootfs, then lzma is compile
by builtoot. If gzip is used to compress the rootfs, then we use
local gzip. It's not very "coherent".
And using compiled binary with buildroot increase chance to
regenerate firmware on (very) different machine.

And I agree with you, it's not a "real" issue, it's more a "nice to have".

Regards,
Philippe

gzip and bzip2 are mandatory dependencies of buildroot 
(http://nightly.buildroot.org/manual.html#requirement-mandatory). These 
packages are shipped by default with virtually all general purpose distros. 
What problem are you trying to fix besides consistency?
