 Yes, I know that. It's why I asked.

I see what you're saying now, they are recommending it even if you don't
use GPT, using a DOS partition table instead? I don't see the sense in
that because you cannot set the appropriate partition type anyway with a
DOS partition table? I suppose it could make switching to GPT at a later
date less painful.

First, Anthony identifies but one popular need for gentooers with advanced
skills to want (and highly desire) a robust method to install new gentoo
systems. So it's not just the noobs, but devs and everybody in between that
knows  that this is a good idea. What do we end up with ? I'd hope several
different approaches to installing real hardware as well as virtual
hardware. The faster/simpler/error-free the better, imho::YMMV.

Anthony's works is alpha so guys like yourself, with tons of experiences,
could provide him ideas. You'll find he's quite a wonderful dev to work
with collegial is a very accurate term to describe Anthony as a dev.


 I see one major problem with a pointy-clicky YaST/Ananconda type
 installer: who is going to write it? Who has that particular itch bad
 enough to scratch it?

Rich0 said he'd modify the handbook into an experimental prose that
leads to a raid-1 btrfs baseline system, if enough folks liked the ideas.
I think that approach is best, because it makes all the 'die_hard handbook
fans happy and can also server as a preliminary specification to an actual
automated installation, not just for noobs. Add a dose of 'snapshots'
(snapper) and we'd have a much better support semantic for noobs and the
rest of us too!

Yes, but they are inter-related issues, imho. Yes I like what you are
saying. There are several needs here for automation of gentoo installs; not
just for noobs, but for those of us trying to develop or stabilize other
codes. HDFS, sucks as a distributed file system. HDFS is the source of many
problems found in modern clustering. For me, I'm spending way too much time
on trying to find an automated (semi-automated) install semantic for
raid-1_btrfs. So my work on mesos [1] is very slow, ATM. Fix the
installation problem, and I'll deliver (toes crossed tightly) the most 'bad
ass' clustering technology currently available::

*Mesos + spark + storm + tachyon + cassandra*  on gentoo (amd64). 

Then the stabilization  work moves to arm64. Both platforms on top of
btrfs/cephfs is going to be *smokin_wicked_cool*. Built from sources, gentoo
will be quickly adopted by many expert linux types. The baggage/packaging
problems, kernel tuning and optimization needs puts Gentoo in a unique
position to dominate this space...


That's my position and I'm sticking with it

Sorry for putting you on the spot. But, there is a multitude of good

No worries! I'll predict that this (raid1/btrfs) is going to be 'massively
successful' as an addition to the handbook, for a wide variety of reasons.
Btrfs on top of cephfs is the best FOSS distributed file system currently
available in open source form. 

Commercially supported DFS, like BeeGFS have one foot in the opensource
world (client side) but I'm not sure the rest of the code is 'palatable' to
the FOSS world and gentoo devs. [1] This site has several interesting
documents on beeGFS; as it is being utilized by some very  aggressive folks
when it comes to HPC. It's worth watching. Btrfs/Cephfs gets the rank and
file gentoo community into Distributed File Systems; and that's a very good
idea, imho. This combo supports RDMA (RoCE) [2]


Cephfs + btrfs have both been aggressively supported on arm8v. So both
embedded gentoo on arm8v and servers based on chips like the AMD arm64
server chipsets are all set to 'rock and roll' as soon as these devices
start shipping in quantity (~christmas 2015).

If you use GPT on a motherboard with BIOS, you need that partition.

FWIW, my notes are at:
https://docs.google.com/document/d/1VJlJyYLTZScta9a81xgKOIBjYsG3_VfxxmUSxG23Uxg/edit?usp=sharing

I plan to clean this up for a blog and perhaps wiki article.  However,
anybody should be able to just follow those notes and get a bootable
system.  Note that I skipped some stuff like network setup, but I did
install everything you should need to configure the network.

I've worked through the openrc install, and I'm working through the
systemd install now.  Really the only thing you do different for
systemd is select a different profile, pick the right kernel config,
and enable system in the grub configuration.  For non-systemd you
again pick the non-systemd profile you want, pick the openrc kernel
config, and don't mess with grub.

For UEFI it would need a tiny bit more work, and a FAT32 boot
partition (which I left off - I just did a simple MBR install here).

Feel free to comment on the notes if you want to contibute, or think
that a particular point needs clarification.  Again, these are just
notes and I do plan to wikify it, but I don't necessarily plan to
recreate the entire handbook with these steps thrown in - if anything
it would probably make more sense to just add a few notes to the
existing handbook.  Really the only thing that is btrfs-specific here
is using grub2 (which is the default anyway), the btrfs setup at the
start, the fstab, and installing btrfs-progs.

The kernel is also overkill, being based on the install CD (which
obviously got you that far already, but probably includes a lot of
modules you don't need).  Being an initramfs install the kernel is
modular, so you're only sacrificing kernel build time, not kernel
memory at runtime.

For me, it wouldn't matter if Gentoo had a installer or not.  It still
would be faster to do a fresh install even without a installer.  So, it
doesn't matter really.  Most of the install time is waiting on a
compile, especially on a older and slower machine.

 No way on 32-bit Athlon. I have Athlon-XP. Even with distcc to
 Core2Duo it takes about 10 days of compilation time to build all
 stuff, I'm not counting time to fix all failures here. Well, I have
 3000 packages installed...

He's going to have to compile all the user-space stuff either way
(upgrade or fresh install), so how long that takes is moot.

 For some degenerate value of easier. :-)

 and faster.  A fresh install will take a couple hours. An upgrade will
 take somewhere between a couple days and a couple weeks.

 Seriously, more than a day?

Probably.  There have beens some major changes in the past 4 years.
The last time I tried up upgrade a system that was more than a year
old, it took a couple days.

Portage was unable to resolve a lot of conflects and blockers. I hand
to uninstall a _lot_ of stuff to get to the point where portage could
be convinced to do any upgrades at all.  It would have been way faster
to do a fresh install.

 Now that I've seen several thread responses subsequent to this one,
 I'm leaning towared just doing a fresh installation, but I'm curious
 about what would happen by trying, and how long it really would take.

Give it a try and let us know how it goes.

 It probably is (for some degnerate value of doable).

Hello Felix. You might want to look at these (2) resources if you are
still intent on the upgrade pathway of an old gentoo installation::
