# Getting around the problem that bsdtar cannot set locale
# since en_US.UTF-8 locale is missing on the system.
# Workaround:
# Use tar instead of bsdtar. This way:
#bsdtar() { tar $@ ; }

# After compilation is done, to finish the packaging
# makepkg needs bsdtar again, but since we said
# bsdtart -> tar and only root can change this we have to
# figure out a way around the issue we introduced to
# bypass that OpenSUSE Build System does not set the default
# locale to en-US.UTF-8 which some programs require in Archlinux.
# What could be done is to create the directory:
# $HOME/.local/bin
# which usually systemd accepts as a default path if it exists.
# But we don't seem to have $HOME/.local/bin
# /home/abuild/.local/bin
# set up from start which would make life simpler.
# It is possible to export the PATH variable, prepending
# our newly made /home/abuild/.local/bin in front of it.
# That way, the system will look for our path first, where
# we can modify things and have write access.
# We create links to bsdtar in the system for both
# tar and bsdtar in /home/abuild/.local/bin
# and no matter what makepkg wants, it will end up getting
# bsdtar after we set our links that way.
# Problem solved, and compilation finnishes.
#
# Another advantage with this bug-fix is that all of a sudden
# you can archive your files with file-roller app and doesn't
# need to use bsdtar from commandline if you are currently not
# on Archlinux but need to create source files for Archlinux.
# bsdtar complains about archives made with file-roller normally.
# That was an improvement until bsdtar is reprogrammed
# so it can handle files *tar.xz made with file-roller on 
# other linux distributions that have other archiving software
# (not bsdtar) installed.
#
# Suggestion fro improvement of the OBS service:
# Archlinux just uses a PKGBUILD file which retrieves
# the sourcefiles without the additional download step.
# It should be possible to set up a download service of 
# the required sourcefiles directly without having to manually
# set the software to download. PKGBUILD often uses and
# https://my.planet.org/archive/${pkgname}-${pkgver}.tar.xz
# which has variables that are set upon activation.
# OpenSUSE Build Service should have the same capability and
# like makepkg fetch the files needed itself, and create the
# download service itself if it needs to do it. That would make
# life easier and the packages would be easier maintained.
# A change of version in one line would trigger downloading
# updated code.
#
# End of observations with OpenSUSE Build Service for Archlinux, Manjaro...
