One reason the Omnibus package is more reliable is its use of Runit to restart any of the GitLab processes in case one crashes.
On heavily used GitLab instances the memory usage of the Sidekiq background worker will grow over time.
Omnibus packages solve this by [letting the Sidekiq terminate gracefully](http://docs.gitlab.com/ce/operations/sidekiq_memory_killer.html) if it uses too much memory.

This guide is long because it covers many cases and includes all commands you need, this is [one of the few installation scripts that actually works out of the box](https://twitter.com/robinvdvleuten/status/424163226532986880).

If you want to install on RHEL/CentOS we recommend using the [Omnibus packages](https://about.gitlab.com/downloads/).

For example many people run into permission problems because they changed the location of directories or run services as the wrong user.
