Sorry for my late reply, i was very busy with my day job.
If all the Arch repositories are active, how come things that exist in Arch can't be found?
# pacopts origin obarun
https://wiki.obarun.org/doku.php?id=pacopts# origin
this will give you what package come from a given repo. all repo declared at pacman.conf can be used as target :
# pacopts origin extra
hope that i understood your question correctly...
And now I am going to do research on how to access AUR from obarun.
you may have different way to accomplish this, can be :
- pacopts aur
- using cower directly
- install yaourt
- install every package you prefer to install aur package e.g pacaur
But grub, whether from chroot from the installer or other chroot, didn't fix grub. For some reason the kernel that comes with the installer will not boot and linux-zen although installed right grub would not pick it up. update-grub does not work on the obarun grub. Grub-install works but you have to edit the grub.cfg manually around that kernel to make it work.
Grub and kernel are not provided by obarun repo but by Archlinux repo, so classic package. The kernel installed by the installer is the last kernel found in Archlinux package, this package is not touched by obarun and the grub package too.
I cannot help you about grub because i don't know how to deal with it, i do not use it.
In all case the configuration for bootloader even if the syslinux package is used, need to be made by the user. This is specified by the installer when you try to install it :).
