Common Tasks
================
.. note:: This page is a work-in-progress stub.
Installing and Running Debian Linux on a SATA Disk
----------------------------------------------------
These instructions will result in a system that boots u-boot and the Linux
kernel from the internal microSD slot, then loads the rootfs and entire
userland operating system from an ext4 partition on a SATA hard disk.
In addition to increased disk capacity, using a SATA disk as a rootfs should
vastly improve disk I/O and thus general system performance.
Connect the SATA disk while the system is powered down, then boot up from the
microSD card. Note that there are two SATA-like connectors on the Novena
mainboard: one is for power from the battery board, and the other is the actual
SATA connection. It isn't possible to connect to the wrong port because the
polarities are flipped. It's strongly recommended to use some form of an
enclosure or mechanical support to prevent the SATA disk from coming detatched
while in use, which could obviously result in data loss.
First make sure required tools are installed::
sudo apt-get install parted debootstrap
We're going to assume that the SATA disk is blank and unpartitioned, and **all
data on the disk will be overwritten**.
We're going to use the offical ``novena-image.sh`` install script. Checkout out
xobs' novena-image repo::
sudo apt-get install apt-cacher-ng
cd
git clone https://github.com/xobs/novena-image
You'll almost certainly want to install apt-cacher-ng and change the mirror
setting (in sata-install.sh) to '--mirror
"http://127.0.0.1:3142/http.debian.net/debian"' (the default is a debian mirror
in Hong Kong). We recommend copying ``sata-install.sh`` to ``local-install.sh``
and making changes there. See the `novena-image.sh documentation
<http://kosagi.com/w/index.php?title=Novena_Image_script>`_ for more details.
To configure the kosagi repositories by default, you can download the
kosagi-repo debian package and kosagi signing key with::
# WARNING: this isn't a secure way to verify the signing key
gpg --keyserver keyserver.ubuntu.com --recv-keys 03C7B7EC
gpg --export 03C7B7EC > kosagi.key
# WARNING: https is not available for this server
wget http://repo.novena.io/repo/pool/main/k/kosagi-repo/kosagi-repo_1.0-r1_all.deb
wget http://repo.novena.io/repo/pool/main/n/novena-eeprom/novena-eeprom_2.1-1_armhf.deb
wget http://repo.novena.io/repo/pool/main/n/novena-firstrun/novena-firstrun_1.4-r1_all.deb
If you are running from the microSD card and have limited space, you'll
probably want to cull down the default installed package list significantly.
Here is an example ``local-install.sh``::
#!/bin/bash
if [ -z $1 ]
then
echo "Usage: $0 [device]"
echo "E.g. $0 /dev/sda"
exit 1
fi
echo "Constructing a disk image on $1"
exec sudo ./novena-image.sh \
-d $1 \
-m "http://127.0.0.1:3142/http.debian.net/debian" \
-t sata \
-s jessie \
-k kosagi.key \
-a kosagi-repo_1.0-r1_all.deb \
-a novena-eeprom_2.1-1_armhf.deb \
-a novena-firstrun_1.4-r1_all.deb \
-l "sudo openssh-server ntp ntpdate \
vim powermgmt-base i2c-tools"
When ``local-install.sh`` looks good, run the script::
# WARNING: VERY DANGEROUS COMMAND!
sudo ./local-install.sh /dev/sda
To actually boot from SATA you must set a flag in EEPROM. Run ``novena-eeprom``
and take note of the Features list, then add ``sataroot`` to the list and write
it::
# Edit this list for your board
novena-eeprom -f es8328,pcie,gbit,hdmi,eepromoops,sataroot -w
The ``novena-image.sh`` script should have taken care of setting the SATA
disk's ID correct, so you're ready to reboot!
After booting into this fresh system, you might want to loop back to the
:doc:`quickstart-board` page. A few errata and things that might pop up:
- need to fix /etc/apt/sources.list to remove localhost prefix (from
apt-cacher-ng)
- run ``apt-get install -f`` to fix any outstanding apt issues
- need to add ``deb http://repo.novena.io/repo/ jessie main`` to get kosagi
updates
- if they aren't already installed, run ``apt-get install novena-eeprom
kosagi-repo novena-disable-ssp novena-usb-hub`` (etc)
- need to create a user (``adduser``, then ``usermod -G`` to add to sudo group)
- need to install a fuller set of packages if only a subset were installed to
save disk space earlier
