Hi,
We are working on a remix(considering a spin) of Fedora that could be used
in schools[1], The problem is, most of these schools in India use donated
computers and have very less memory (256 Mb - 512 Mb).
According to this blog post
https://anonbadger.wordpress.com/2011/02/25/need-more-memory/ and this email
thread
https://lists.fedoraproject.org/pipermail/devel/2011-February/149110.html i
understand that some one is working on reducing the memory footprint of
anaconda.
Will it be ready for F16? How much memory will anaconda require to install
Fedora 16? I'd love to see reduced memory requirements for anaconda in F16.

The "treebuilder" branch of lorax, where such a project is being developed,
is not complete today.
How much memory will anaconda require to install Fedora 16?
Anaconda requires 768MB, and more (>=1GB) if there is no swap partition.
I'd love to see reduced memory requirements for anaconda in F16.
Use the installer that is available on a Live spin, instead of using
anaconda. Being "live" (running from media without install) might
have other advantages in the stated environment: try-before-install
(without modifying the harddrive), etc.

This reduces the memory requirements by 128MB:
Fedora-15-i686-Live-Desktop.iso
Fedora requires 640 MB of memory to install, but you only have 256 MB
on this machine.
And even creating swap space in advance does not help - but a fix is underway:
Fedora 15 Live refuses to install to disk on 256MB RAM, but installs fine with 2 simple
workarounds

Would it be possible to create a custom image that just does a minimal (possibly
text-based) install? This might reduce memory requirements even more, and extra
packages could be added later - the DVD could be used as a repo if bandwidth is
an issue.

It is not just Anaconda. F15 GA kernel would not even uncompress
initramfs on anything below 1GB.
On VM hosts, I modify the VMs with virsh to have 1GB, then scale them
down after installation.
This is getting difficult to manage, I have to say. My almost brand
new Red Hat corporate T400 only has 2GB, and I have a stack of almost
good enough boxes. In the past we always felt free to push obsolete
hardware over to BSD. Remember NPTL? CMOV? But now I have a feeling
that we may be outstripping the speed of improvement in common hardware.
Or maybe I need a better computer.
I'm wondering what everyone's feeling is about it. I saw a tweet (by
Mairin, I think) "the 12GB is a life-changing experience". Well, if
that's our new standard platform, then sure, no sense to optimize
for 1GB.

The initial post was very good at citing several sources which make it
clear that the high requirements of F15 and current F16 are a temporary
aberration, so I'm not sure this essay on how evil they are was really
warranted. The anaconda team are very well aware, and working to reduce
the requirements. The thread was a simple question about time frames.

It is not just Anaconda. F15 GA kernel would not even uncompress
initramfs on anything below 1GB.
There must be some caveat to this, as I am running F15 on a machine with
only 512 MB of memory. I had to install F14 and upgrade to F15 to get there,
but once set up, things work fine.

In Fedora 15, all of the "stage2" content, that is anaconda and supporting
libraries, were made part of the initrd. This was a change from previous releases, where
the initrd was just stage1, that was enough infrastructure to find and launch stage2.
Moving it into the initrd resolved a lot of outstanding issues with Anaconda, and removed
a lot of duplicate code that was difficult to maintain.
There was a jump in memory requirements, as now all of that content was loaded into
memory, and there are potential fixes being worked on. However they were deemed too risky
for Fedora 15 and thus did not make it.
This is why the install kernel requires significantly more ram than the kernel you'd
use after you've done an install.

Arun, lets use live installer. Anaconda won't help in schools. Live,
anyway, has its advantages and kids/teachers can check it out before
installation.

Hello,
what about using the Text Mode for the install? [1]
According to the release notes it only needs 256MB of RAM so I think it
should be feasible, or? [2]
Are there anything preventing the usage of the textmode?
Best regards,
Johannes

Unfortunately, those numbers are way out of date. See the comments in
https://bugzilla.redhat.com/show_bug.cgi?id=682555 . Currently, it requires at
least as much RAM to do a text-based install of F15 as a GUI install, which
doesn't make sense, and is why I asked whether it would be possible to make a
custom image to do a minimal (possibly text-based) install using reduced memory.

FYI - The installer on live *is* Anaconda. The primary difference is
that it doesn't use yum to install the system, it copies the live image
to the target and resizes it. This avoids several large memory hits that
happen during package install.
