I agree that it'd be "acceptable" in the sense that the miniroot isn't
the operational system, and tricks there could possibly be defended,
so long as they don't require extreme (and thus unsupportable)
contortions.
I seriously doubt that it'd reduce any RAM usage, though, so exploring
it seems pointless. The RAM usage is mostly a factor of the amount of
code and data on the disk, not the way in which it's linked. In fact,
static linking is *worse* because there are no shared copies of .text
segments.

Yes. There are two notches of RAM that can be cut down, depending on
how much effort can be expended and the desired outcome.
1. Finish Caiman and rid the miniroot of the vestiges of the old
installers and upgrade systems. They're baggage, and the sooner
we jettison them, the sooner we pare down the required miniroot
size.
2. Give up on the idea of having a fancy, nice-looking, loaded with
features installer. Go back to a simple, plain-text,
curses(3CURSES)-based, circa-1981 system.

I'm not in that group, but my understanding of the trade-off here is
that they're deliberately abandoning old systems. We're no longer
designing for the "3M" systems that were the holy grail when I was in
school, and design points change over time.
("3M" doesn't refer to the midwest company. It means one megabyte of
RAM, one million instructions per second, and one million [monochrome]
pixels.)

I know all this. Inspite of that, I believe static linking just for the installer is acceptable. The binary will be bigger, patching and sharing as far as miniroot is concerned are in my opinion completely irrelevant, because miniroot is something that must be dynamically generated for every Solaris / Nevada revision anyway. Let's spin this around some: I've read quite a number of reasons why it shouldn't be done. Do you have a better idea on how to bring the ridiculous requirement of 512MB of RAM just to install Solaris down? The end result is, no matter how you slice it and dice it, that Solaris can't readily be installed on systems that have less than half a gigabyte of RAM. And that's the "slim" installer! Now, I know you guys at Sun have super-di-duper shining U20s and U25s, but there's literally milions of people out there which have systems sitting around which would make for nice little servers with 256MB of RAM... if they could only install Solaris on them.

I never said it's impossible. I said "it's not happening". I can not imagine
that someone would take on this project.
Basically with all the trimming you would need to do to fit, and the amount
of RAM modern browsers take to run, combined with the performance
characteristics of the device, it would be a lot of work for little benefit.
256MB is passable for a server, but not so hot for a day to day desktop.
(GUI apps: Browsing/flash video/javascript heavy apps/mp3s, OpenOffice,
etc).

Why ? I only have 256MB in my Ultra5 and crafted most of the
ksh93-integration stuff on that machine. And disk space shouldn't be a
big problem since much stuff can be trimmed, redundant stuff removed
(e.g. the extra libc, 64bit stuff, includes etc.), Xserver linked
statically etc.

I see those have a 2.5" hard drive in the 3850PS, but it looks like that might be a little bit bigger.

The disk footprint of a fairly minimal install, with enough to run X and some sort of desktop (twm, for example) is in the 200 megabyte range. You can get a lot onto a CD - still well under 1G (slim install is just over half that). Until recently I had a production server running S10 that only had 256M in it. It worked fine. Basic desktop use will work fine in rather less than 256M. You'ld have trouble with gnome as currently built (medialib bloats the running sizes quite a lot, but that could be trimmed), and I certainly don't think you would enjoy running much in the way of java or staroffice.

There was some experimentation done with a prototype OLPC
board and BeleniX. One person was able to get BeleniX booted
on the OLPC from an external CDROM drive but faced some
issues with processor extensions used in the math library. So
init was crashing.
This was with a prototype board using a standard BIOS. But OLPC
now uses LinuxBIOS. Osol can be made to boot with LinuxBIOS:
http://blogs.sun.com/szhou/
The OpenSolaris kernel can boot and work in OLPC and 256MB
RAM should be enough to run a lightweight GUI. Some stripping
of modules are definitely required, including having a minimal
Xorg.
Keeping a controlled set of apps will be enough to fit Osol onto
a small footprint diskspace. There is a lot that won't be required
in the OLPC environment.
The difficulties I see are having a lightweight filesystem for the
Flash storage with compression support. ZFS is a little too heavy
for the OLPC application domain.

I would say Linux is the better choice, but only because embedded Linux has been stripped down and made to fit in those types of environments. The old mini-root used to load on a 64mb USB and boot from it, with a little bit to spare. If one was to incorporate BusyBox you can certainly get a working system in 1G, IMO. To give you an idea of how small Linux will fit into though, I worked on an embedded Linux device that Linux would boot and run in 8MB of ROM, 8MB of NAND, and 16MB of memory. That would be very difficult for Solaris. However, 256mb of memory and 1gig of storage, I think it would be doable. As to who could do it, what about the person that was asking?:-/ You've got the sources.;-) -- Alan DuBoff - Solaris x86 IHV/OEM Group ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

Not happening. You only have 1G of storage. Solaris would need some
serious trimming to fit. (And maybe compression). With 256M of RAM it
would be crazy.. Here Linux really is the best choice. (The eee on the
other hand, might be doable).
