The job description I responded to:
IT Guru
Systems support engineer needed for total IT support of highly mixed platform environment including Linux, FreeBSD, Mac OS X, Windows, and Cisco OSes. Tasks range from the exciting to mundane. They include maintenance of production-level servers (Sendmail, Bind, and Apache), firewall and VPN configuration, developing backup strategies, writing automation scripts, hardware specification and installation, installing server and desktop software, and fixing the damn printer (again).
I don’t think anyone can say I didn’t do that and didn’t do it well.
