Keep the commented ParallelDownloads in pacman.conf
/etc/pacman.conf is edited for the docker with this content:
# We cannot check disk space from within a chroot environment #CheckSpace
#ParallelDownloads = 5 is fully removed from the file, but that config line is in the
pacman.conf at the root of this project.
Could we recheck that replace? I didn't find the code who is making this replace yet.
