Hello Yann E,

I am sorry to cause your confusion. This is an imaginary example I give.
I've already explained this issue in the email that responded to Thomas Petazzoni.

my filesystem is xfs of centos7.
Sorry.This problem is likely to be one of my mistake rather than 'per-package'.
That day I encountered a compilation error 'toolchain HOST_DIR' which had been reported to Thomas Petazzoni.
The details:
when run the command 'output/per-package/toolchain/host//usr/bin/mips64-octeon-linux-gnu-gcc  --version'.
there will raise a error 'output/per-package/toolchain-external-custom/host/opt/ext-toolchain/bin/mips64-octeon-linux-gnu-gcc: No such file or directory'
When I encountered this error. I made a patch to solve it.
But after I saw thomas reply, I carefully checked my patch and I found out that my patch duplicates the toolchain-tar in the per-package/ package which dependent toolchain.

I am currently testing per-package. I have not finished all the compilation.
I have encountered many problems, of which some are my own environment issues and others are per-package issues.
I am trying to solve these problems to promote its progress.
Hopefully per-package SDK can be pushed into the mainstream as soon as possible.

Chu,Zhuliang
