As discussed with @librehat in #1604, maintaining a separate set of systemd
files for RPM distributions will be convenient to build on Copr.
This patch will also change some lines in rpm/genrpm.sh to archive the
source code using `git archive` because the old logic doesn't respect
`.gitignore`.
This patch is going to replace the group name 'nogroup' with 'nobody' in
debian/shadowsocks-libev.service, and move file
'/etc/default/shadowsocks-libev' to '/etc/sysconfig/shadowsocks-libev'.
This is implemented by creating a text patch file. Not sure whether
there is a better approach.
it's not conflicted with shadowsocks-python now. users can install both python and libev
ports of shaowsocks now. but they should migrate their old configuration file from
/etc/shadowsocks/config.json to /etc/shadowsocks-libev/config.json
