accessing internet in post section when creating live image

[Vojtěch Polášek]

Hi,

my name is Vojta and I am a blind programmer from Czech Republic. I am 
trying to create a special live image for blind and visually impaired users.

I have experience with kickstarts, this is the project I am trying to 
turn into live image:

https://github.com/vojtapolasek/Fegora

In the %post section I try to clone some git repos and build something 
so that I can later put it on the live image. Is that possible? Because 
it seems that I can't access the internet within the %post section.

Thank you,

Vojta

If you are not cutting off internet access explicitly (or running it
in a build system that will do that automatically, like Koji does),
then you can. However, it is likely that DNS will not be working
inside the chroot that %post runs in because the /etc/resolv.conf file
is not populated. You could populate it temporarily, and then reset it
back after you're done so that the live media will correctly detect
and auto-populate DNS settings on boot.

Hi,

thank you very much, this helped. Maybe it would be nice to have it 
documented somewhere...
