Clean up default software to get to a (mostly) standard distro?

[chrism...@gmail.com]

Hi everyone!

I just got my BBB rev C in the mail on Tuesday! Super excited about it too :D

What I'm wondering is - there's a lot of extra software on the system that I don't really need. Is there a list somewhere of all of the specialized software that's installed, so that I can take the system back to a more standard setup? Eg., I'd rather have Apache serve out over port 80, rather than whatever's doing so currently, and I don't need the developer tools on the board itself (I'll put them on my other computer.) I don't really need all the X stuff either. For the most part, I just want a basic server (that I can install some additinoal software to) that can be used to access all the GPIO, UARTs, etc.

Thanks!
Chris

Well, the factory image was based on this image:

http://elinux.org/BeagleBoardDebian#eMMC:_BeagleBone_Black

So, reflashing that image would be easier then to tell you which of
the 600 packages was added ;)

Chris,
I have found this site to be useful

Enjoy and be prepared to re-flash and re-install software several times.

Those are some good links.  One of the new BBB Rev C units I just got had a bad HDMI port and so I had to send it back for RMA.  When I got the repaired unit back it had angstrom on it so i had to figure out how to flash it back to debian.  

The instructions here:

• http://hifiduino.wordpress.com/2014/03/17/beaglebone-black-base-operating-system/ 

look good except that I'd be sure to get the latest "flasher" image from here: 

• http://elinux.org/BeagleBoardDebian#Flasher
  

Updates seem to happen on a monthly basis:

• 2014-06-05
  • BeagleBone Black: v3.8.13-bone56 kernel
• 2014-05-06
  • BeagleBone Black: v3.8.13-bone49 kernel
• 2014-04-18
• BeagleBone Black: v3.8.13-bone47 kernel

One of the nice benefits of this experience (ordeal?) is that I got a base or bare minimum debian install with none of the fluff and there was even some hardening done as far as the usernames and passwords go.  

Below I will share some of the details for your consideration.

Here is the disk usage with the original factory image: 44% full using 1.4G of the 3.4G on board flash.

I also restored the password settings so I could login with no password.

passwd -d root # to clear the password 

vi /etc/pam.d/common-auth # change the line below

pam_unix.so nullok

vi /etc/ssh/sshd_config # To enable empty passwords, change to yes 

PermitEmptyPasswords yes

If a minimal system is what your after I recommend buildroot. It takes some effort but it can be made very minimal...

Or one could always use Robert Nelsons barefs and just replace the rootfs / install what you want / need via apt-get install.
