Interestingly I switched from Linux to FreeBSD around 2002, primarily because I was frustrated with Linux sysadmin. Perhaps I was more of a newbie but the inconsistencies in Linux system organization and the confusing, low quality, half-obsolete docs, and unbounded time required for troubleshooting were some of the reasons. When I switched to FreeBSD and started using ports, my sysadmin time dropped significantly. But I was only using a single system.
