[ARMedslack] Running armedslack on boards with LESS then 64 MB of ram.

[Andrzej Telszewski]

Hi,

I have this board: http://boff.pl/?shop=1&p_id=5
I have custom kernel (2.6.32.9) with among others the Virtual Terminal 
support disabled.

I have pulled today's current and the installation went without any 
problems. It seems that the system boots correctly, here are some info:

tmpfs                  15M     0   15M   0% /dev/shm

rc.udev remains with "mount -n -o mode=0755 -t tmpfs tmpfs $UDEV_ROOT" 
unchanged.

As I don't have VT support I have also commented out c1-c6 from 
/etc/inittab.
