interesting. Yes, there are a lot of hidden features...

Well, I have a ./mgta04 script which does all the builds and packs and
copies results to a directory and takes the current git branch name so
that I always have older builds (separated git branch names) for comparisons.

And I have a ./dl script which installs things on my SD cards. It usually
installs the current branch but if -b is given I can also install an older
branch. So these scripts know what to do and copy separate .tbz for kernel,
modules and device trees. But they are not generic enough to be published

If I run ./dl -p things are published to the server and appear e.g. here:

I usually have them unstripped (although this needs a lot of disk space)
but the flash-nand script strips them before flashing. Since the typical
NAND is less than 10% of my typical SD cards and every byte counts :(
There I also filter the modules that are really loaded by the kernel.

The only problem I have with unstripped modules is that it takes quite
some time to upload them to the Goldelico server through the Internet.

Looks reasonable. And although I have no use of it, others may find it
beneficial and the discussion on LKML will certainly give a lot of feedback
(let's hope not too controversial).
