This does't work: ExecStart=/home/deploy/.rbenv/shims/bundle exec sidekiq -e production -C config/sidekiq.yml -L log/sidekiq.log
This works: ExecStart=/bin/bash -lc 'exec /home/deploy/.rbenv/shims/bundle exec sidekiq -L log/sidekiq.log -e production -P tmp/sidekiq.pid'

It's about /bin/bash -lc at the beginning.
