great!
added nethserver-devtools and nethserver-mock, installation went fine… keep us informed. tnx
I’m surprised too, thanks for starting this compelling topic! There are many amazing people around here 
Just rebuilt my mock cache, all seems good so far.
EDIT:
http://mirror.framassa.org/nethpi/7/base/armhfp/repodata/repomd.xml: [Errno 14] HTTP Error 504 - Gateway Timeout
I’ll try to review mock.cfg in the weekend, I’d like to add it to the wiki page.
Next step: cross compilation. Anyone has experience in this matter?
yes server is down, i hope to check it in the afternoon sorry 
EDIT:
@filippo_carletti can you try now? tnx
This is great!
Not on CentOS and the like. Centos has a cross compiler package, but i can’t figure out to build a tool chain.
If there is a mock.cfg to make nethserver-packages om arm, i’ll think a arm devel-setup will do. the packages are relativlie small. I was looking in to it bçause under some circumstances build dependancies can be met by the build-host (i.e you need this in your tool chain, x86 lib will do)
BTW i think they are done (re)building the hole epel repo; today the repodata showed up in the devel repo’s
That’s critical, we need epel packages for many modules.
Here’s my mock cfg. Put it in /etc/mock/ and set
mockcfg=nethserver-7-armhfp
/etc/mock/nethserver-7-armhfp.cfg

If anyone interested, we can also try the build infrastructure from CentOS for arm64: http://cbs.centos.org/koji/hosts
Ran out of hardware to test this (monitoring install’s with munin)
Could not resist and bought a PI3, gone have a go soon

LOL me too yesterday… 
Also because tomorrow I must return the rpi2 i’m using for testing to my friend
@jackyes CentOS still uses the “noob” config.txt, under-clocking the rpi3 on 700 MHz.
Do you know moderate (stable) settings for clock/core/dram and the like?
@dz00te @giacomo hesitated long to get a RPI3 because an eye on this:
http://www.hardkernel.com/main/products/prdt_info.php?g_code=G145457216438
My pi3 stabile at 1300mhz, SDRAM freq 400 overvolt 2. More than this became unstable.
On my friends pi 1400mhz,SDRAM freq 500 ,overvolt 6 without problem.
Try a mid valute from these settings 
After that, to increase performance set the scaling governor to “ondemand” or “performance”:
echo “ondemand” |sudo tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
If set on demand, change the up thresold limit from 95 to 60:
echo 60 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
With this the CPU freq go up when the CPU load is more of 60%.
This can greatly improve the performance of the pi 
It’s a good idea to use a heatsink because the temp go up much more than the older pi
This is very cool!!
The Good news is it does build Nethserver packages
Bad new is I can’t get them installed 
Transaction check error:
file /usr/sbin from install of nethserver-release-7arm-0.1.24.ge946f89.ns7.noarch conflicts with file from package filesystem-3.2-18.el7.armv7hl
Did not change much just two typo’s messages.
EDIT:
EDIT 2: fixed this fault in spec file and installed successful
Trying to build a new nethserver-mock for arm threw up this:
DEBUG util.py:468: Executing command: ['btrfs', 'subv', 'list', '/var/lib/mock'] with env {'LANG': 'C', 'TERM': 'vt100', 'SHELL': '/bin/sh', 'HOSTNAME': 'mock', 'HOME': '/builddir', 'PATH': '/usr/bin:/bin:/usr/sbin:/sbin'} and shell Fa$
DEBUG util.py:393: ERROR: can't perform the search - Inappropriate ioctl for device
Any clues? (I saw mock message selinux enabled could that be a clue???)
The package contains the /usr/sbin directory inside the %file section, you should remove it.
Please paste the spec file
Odd, i have used this spec file from the beginning…

.....Are you using nethserver-mock and nethserver-devtools from @dz00te repo with my mock.cfg file?
I think you don’t need to rebuild nethserver-mock, it’s noarch.
yes
just did this for test exercise (added your mock.cfg)
The nethserver-devtools provides the genfilelist script and the one from ns6 branch wants to own any directory, like /usr/sbin. On ns7 I’ve fixed its behaviour. Could you check the nethserver-devtools version that is downloaded during mock builds?
Mine is nethserver-devtools-1.1.4-1.5.ga337344.ns7.noarch.
