Notes
on a hard drive installation of exGENT
1. You
need to install exGENT on an ext3 partition. You
must ensure that the current partition is created and formatted before
you start the installation. Run
the command mke2fs -L / -I
128 -F -j -O dir_index /dev/sdaX
NOTE:
You must
use this command when formatting. Your Grub Legacy installation won't
work otherwise.
2. Before
you can format, you must unmount the current install partition. This is
done with the command umount /dev/sdXX. ("X"
must of course be replaced by the letter and number of your current
partition, e.g. /dev/sdb7 or...).
3. You
should/must also create a SWAP
space of about 2000 MB.
IMPORTANT:
Be sure to unmount ALL partitions on your
computer before you proceed.
Then follow these steps:
1. So
first create a Linux partition of about 20 GB and a swap space of about
2000 MB. If
you use an existing Linux partition, you must make sure it is formatted
before running the commands listed below. Hereinafter
the Linux partition /dev/sdb7 and SWAP partition /dev/sda2. (You must
of course enter the correct name for your new or already existing Linux
partition and SWAP partition).
2. Boot
up the computer from the exGENT cd and open up a terminal as root.
3. Run the command umount
/dev/sdb7 (if mounted)
4. Run the
command mke2fs -L / -I 128 -F -j -O
dir_index /dev/sdb7
5. Run
the command cd /root/install
6. Run
the command ./install.sh /dev/sdb7 /dev/sda2 (IMPORTANT:
The correct order of the installation partition and the SWAP partition)
7. If
you do not already have a Linux system on your computer and want to use
Grub2 as boot loader, you should eventually run the command ./install-boot.sh
/dev/sdb7 /dev/sda (Comment:
This will install Grub on the install partition and in MBR - /dev/sda).
Done!
See
below how it looks when the above installation commands are executed.
Check Grub (/mnt/sdb7/boot/grub/grub.cfg)
Before you restart your computer after a Grub install you should mount
your install partition and check that the install program got it right.
Check especially line 5 - see below set
root=
'hd1,gpt7'. If you have installed exGENT on (for
example) /dev/sda5 said line should be set root='hd0,gpt5'.
Grub2
If
you are using Grub2
(new GRUB) as boot loader, you should instead add the following lines
in the file /etc/grub.d/40_custom and then run the command
update-grub (in the system where you have installed Grub2).

NOTE:
When installing exGENT in VirtualBox or VMware you should start up your
installation from the hard drive and then run this command: grub-mkconfig -o
/boot/grub/grub.cfg
If you do that you will get a much nicer Grub2 boot screen- see a screenshot.
GRUB
Legacy installation
If
you are using Grub Legacy as boot loader, add instead the following
lines in GRUB (menu.lst) and restart your computer. I.e.
edit /boot/grub/menu.lst on the Linux partition where you have
installed GRUB Legacy in the past.

To do after a hard drive install of exGENT
First you should open up a terminal and run the commands source
/etc/profile followed by emerge --sync.
After that you can install new packages (for example Libreoffice).
Command emerge --ask libreoffice. That way you'll
get to know dependencies and if you have to make any changes to the
file /etc/portage/make.conf before you can go on and install
LibreOffice with emerge libreoffice. Please read
about Gentoo's
Portage (package manager) before you install any programs. You can also (if you like) use Porthole
Package Manager, which is preinstalled in exGENT version
170309. Porthole is a front-end for Portage, the Gentoo Package
management system. It allows you to browse through available software
packages and install them easy as pie. You can for example
install the LXDE
Desktop Environment. It will look like this.
Create
new users
Maybe you want your own ordinary user after a hard drive install. This
is done (as root) with the following two commands:
useradd -m -G users,audio,wheel username
passwd
username
Good luck!
