:-)
the funny thing is that SunOS has been bootable into ramdisk since... forever.
Back in the day, before CDs were invented, we booted from tape or (if you really
hated yourself) floppies :-). Net-net, this probably isn't documented anywhere, 
per se,
outside of the building shell scripts :-(

The way it works is to produce an image of a file system. Add that to a boot 
loader
and instruct the boot loader to put it in memory and run. The actual work is to 
produce
the image, and this is where the build scripts comes into play. You can 
certainly take
an OmniOS build and produce an in-memory root, however, the missing management
part is handling the persistence of identity. For that, it is useful to see how 
SmartOS
handles /var and files normally modified in /etc.

I’m booting off of a pair SLC USB sticks today. 

They’re extremely fast boot still not as fast as SmartOS running in 
memory. 

I guess I’ll do some googling to get omni running in memory :p

The next big thing seems to be M.2 PCIe cards, which are a whole lot 
faster.  Hopefully they will work with OmniOS.  I have two Samsung

booting from a good pair of 32 GB USB sticks is possible.
(Turn off atime)

But I would prefer a pair of 32 GB DOMs like

[John Barfield]

I’ve been interested in configuring omnios to run in memory off of a ram 
disk myself. 

Does anyone know where you could find a good guide for booting Solaris(h) 
kernel into memory with a ramdisk?

No.  We boot off of traditional media.

[OmniOS-discuss] OmniOS considered in-memory OS ?

[Mick Burns]

As per current wikipedia entry for SmartOS,  we can read the following :

 "SmartOS is an in-memory operating system and boots directly into
random access memory. It supports various boot mechanisms such as
booting off of universal serial bus thumbdrive, ISO Image, or over the
network via PXE boot."

Does this statement applies to OmniOS as well ?

Ultimately, what I need to know is if OmniOS is good fit to run OS off
a pair of either internal SDcards or good quality USB sticks ?

thank you.
