[Arm-dev] [question] CentOS 7 Installer ISO generating

[Lomovtsev, Vadim]

Hi all,

With the original ISO and updated kernel using VA length set to 48 bits we got an issue wit polkitd crash because of mozjs can't work with 48 bits VA. There is an open bug https://bugzilla.mozilla.org/show_bug.cgi?id=1143022 but there are not much updates. 

So I applied patch for mozjs, recreate rpm and tested it - works well, no crashes observed. 
For my setup I need to have it installed automatically at system deployment phase using installer ISO. Now every time I need to update mozjs rpm manually along with kernel rpm.

I've tried to repack existing ISO with my rpms (updating packages repository) but in this case anaconda fails to proceed installation due to rpms signing checks of something like that. 
It looks like I need to recreate whole ISO from scratch, or properly update repodata for packages (simple createrepo is not enough) isn't it? 

I believe that I need to use CentOS deployed at armv8 system and use lorax to create an ISO , is that right or it could be built in cross-compiler environment?

We also will need to add some extra packages for KVM support and this could help us also.

WBR,
Vadim
