3. Motivation
Galaxy Quest (1999)
Sir Alexander Dane You're just going to have to figure out what it wants.
What is its motivation?
Jason Nesmith It's a rock monster.
It doesn't have motivation.
Sir Alexander Dane See, that's your problem, Jason.
You were never serious about the craft.

16. UNIX lives on in many of us

17. The motivation
• We have a lot of customers with
“traditional deployments”
(servers, not instances)
• We would likely have bought Solaris 11,
if I could build it from source.
• We needed a path of least resistance for
our Solaris 10 users... that delivered on
the promises Sun made.

38. Kayak Installs Simple Stupid
• Kayak (http://omnios.omniti.com/browse.php/core/kayak)
• builds an altroot install
• zfs sends it (to a file, then over HTTP)
• makes a miniroot (served over TFTP)
• written in shell (sysadmins rejoice)
• tiny python web server (not required)

Packaging: IPS (WTF?!)
Friday, December 14, 12

62. IPS Controversy
✓IPS sucks (yes, like the rest)
✓IPS made new problems to solve
✓IPS is uncommon
Friday, December 14, 12

63. IPS Justification
• IPS builds are part of Illumos
• ipkg zone is something we use
• I’m disaffected:
"It's packaging other people's software
that makes system administrators violent people"
- http://www.youtube.com/watch?v=ieCTIPG43no
• Avoid “solutions:”
I’m looking at you facets
• Minimal use of incorporations
Friday, December 14, 12

64. IPS niceties
• IPS is a network resource
• pkgsend is tool, not a framework
• All HTTP micro assets (cacheable)
• Handles all the BE magic
• Without the “features” it just works
Friday, December 14, 12

65. What we learned.
• We built packages for Solaris 10
...and for Linux ...and for FreeBSD
• Because we’re a snowflake
...just like very one else.
• Rule: “keep your shit to yourself.”
Friday, December 14, 12

66. Minimal: not useful
• OmniOS only ships “core”
• no web server. no database.
no proxy cache. no PHP. no Ruby.
no bind.
• we ship perl, use your own.
• we ship python, use your own.
Friday, December 14, 12

67. Minimal: awesome-sauce
We use OmniOS...
like a layered cake
