[gentoo-user] how to install from ISO without burning it

[Harry Putnam]

I've been looking around for a way to install gentoo just by plopping
an ISO into a known partition,.

I'm not getting much from google on this search string: 
   install gentoo directly from iso.  Or I should say:

I've found a couple of how toos but they involve quite a lot of mumbo
jumbo like this one:

http://nlug.ml1.co.uk/2011/06/boot-livecd-iso-image-from-hdd/305

I can follow that alright but first wanted to make sure there
is not a well established mainstream way of doing it.

Maybe this helps:

Boot the ISO image from the disk using Grub2
http://www.sysresccd.org/Sysresccd-manual-en_Easy_install_SystemRescueCd_on_harddisk#Boot_the_ISO_image_from_the_disk_using_Grub2

Here is my grub config:
set isofile="/systemrescuecd-x86-2.3.1.iso"
loopback loop (vg_8540w-lv_boot)$isofile
linux (loop)/isolinux/rescue64 docache setkmap=sg isoloop=$isofile
initrd (loop)/isolinux/initram.igz

If you use "docache", you are able to unmount your partition after
booting...

I don't know if this works with the Gentoo livecd...

Curious.

I was going to attempt an installation directly from a new liveDVD
11.2 just for grins. Here is what I found. I have not yet found
the time, but it's on my list. Anyone tried this or a similar
method for installation?

Well, AFAIK all you need for installation are chroot, the latest stage3, and
portage-latest. So if you already have a bootable Linux system with a
chroot, you're good to go.

Apparenly ISOLINUX is in a family of very similar bootloaders, and
someone made reference to a disk version of it last week or the week
before.

However, it might be possible to replace ISOLINUX on the live DVD with
the family's disk equivalent*, and have your normal bootloader chain
load it?

I'm missing a lot of detail here; perhaps someone else remembers or knows more.


* surely there's a script somewhere that automates that.
