BR2_PACKAGE_GZIP depends on BR2_PACKAGE_BUSYBOX_SHOW_OTHERS, so you
should select it as well.

Thanks!

I wondered whether to send a patch for each 'select' individually or to 
wait until I complete my testing and submit a single patch with all of the 
lxc selects. What do you prefer?

Both solutions are fine with me. You can send patches as you
progressively discover the issues, or send a single patch fixing all
problems at once.

I'm just wondering if we want to make all these dependencies actually
mandatory or not. It seems some of these dependencies are only used for
one specific tool in LXC. If the tool is not crucial in LXC usage,
maybe we should make it optional via a sub-option? I'm not sure here,
just thinking out loud.

Well, lxc is already in the 'server-class' software, probably to run a
bunch of containers, themselves in the 'bloatware-class'.

So, the overhead of having gzip is probably insignifiant in the face of
the size of the rest of the system.

So, I'm OK with selecting gzip unconditionally.

However, I would not want to force-select BB_SHOW_OTHERS, even though we
already do it in three locations. Well, damn be it, just select both.

Jonathan, care to fix and respin, please?

Regards,
Yann E. MORIN.

[Buildroot] [PATCH 1/1] lxc needs gzip scripts for lxc-checkconfig runtime

[Jonathan Ben Avraham]

Hi Yann,
My current use case for lxc in Buildroot is for mobile SoC's such as the 
Qualcomm Snapdragon 805 and 810 that have IP blocks such as DSP's, VPU's 
and GPU's for which Qualcomm only releases Android drivers and libraries. 
In order to use these IP blocks, I run Android in an lxc and pass CNN 
kernels from Linux to adsprpcd running in Android that passes the CNN 
kernels through the Linux kernel to the Hexagon DSP. Admittedly this adds 
new meaning to the term "Convoluted Neural Networks" but it provides an 
interim solution to the application developers until we can reverse 
engineer Qualcomm's FastRPC interface.

I will re-spin the patch but before that I have yp-tools, ypbind-mt, 
sphinxbase and pocketsphinx to finish.
Thanks,

  - yba

Aha! :-)

Yeah, I can see how containers can come handy in this situation (not
unlike somethig I've had too, btw).

Great, thanks!
