# Partitioning Help
|
|
|
|
## You have an empty drive
|
|
|
|
Cool, easiest way! When you have an empty drive, just start GParted
|
|
and select in the right up corner your correct drive you want to install
|
|
nanodesk on.
|
|
|
|
After that click in the upper Menu the entry 'Drive' and select
|
|
'create partitiontable'.
|
|
|
|
In the upcoming dialoge select 'ms-dos' abd 'Apply'.
|
|
|
|
Now right click in the empty bar representing your drive and select
|
|
'New'.
|
|
|
|
First we create your root filesystem. It gets most of the space, just
|
|
let around 4-8GB space left after free for a swap partition we create
|
|
afterwards.
|
|
|
|
Create as 'Primary' and select 'ext4' as filesystem. Confirm that with
|
|
'OK' and repeat the steps with the leftover diskspace and create a
|
|
partition with the 'linux-swap' filesystem.
|
|
|
|
When you done all this we need to activate our changes. Select 'Edit'
|
|
from the upper Menu and choose 'Apply All Operations' and confirm.
|
|
|
|
When all operations are done successfully, close GParted and click on
|
|
'Install' in the nanodesk-installer.
|
|
EOF
|
|
}
|
|
|
|
help-select-target() {
|
|
|
|
cat <<EOF | $GXMCMD
|
|
$HEADER
|
|
|
|
# target device
|
|
|
|
Here you have to enter the path to your drive with the
|
|
'ext4' filesystem on it. This could be in most cases for example
|
|
|
|
/dev/sda1
|
|
|
|
Which says it's the first drive in the system (sdA) and the first
|
|
partition on it (sda1).
|
|
|
|
If you are not sure, you can abort here and open nanodesk-installer
|
|
again. Open again GParted to verify that you choose the correct drive.
|
|
|
|
# commandline nanodesk-installer
|
|
|
|
In the next step the core of the installer, the commandline tool
|
|
`/usr/sbin/nanodesk-installer` opens up in a new xterm window.
|
|
|
|
Confirm the start of the installation by typing 'YES' all upper case
|
|
and confirm it by pressing [ENTER].
|
|
|
|
When the base system is installed, you can choose if you want to keep
|
|
the default user 'debian' with its password 'debian' (press [K])
|
|
or you also can remove this default user and create your own new one
|
|
(press [U]).
|
|
|
|
# when something goes wrong
|
|
|
|
If the installation proccess exits with an error, you can clean up
|
|
everything by hand:
|
|
|
|
sudo su -
|
|
umount /mnt/
|
|
rm -Rf /tmp/nanodesk-installer.*
|
|
mkfs.ext4 [TARGET]
|
|
|
|
# you can re-run the GUI again
|
|
nanodesk-installer-gxm
|
|
|
|
# or the cli nanodesk-installer directly
