How to Enable DNS (Using PPPD)

[Fernando RUIZ CASAS (E-mail)]

It's possible normalize the creation of a common rootfs tree with 
ALL the files necesaries for each modules but in a shared place?

I can think around /etc files like /dev directory.

In shell.c I have placed a 
 write_file(char * file_name,char * contents)
in order to write a file from a constant. With this I can write 
/etc/passwd, /etc/group & more. 

The first action is call to getpwent("root") in order to 
setup the directories environment making a mkdir("/etc")
in the rtems filesystem startup code like size effect.
I would to have all of this in a more friendly way.

I can think about the tcp/ip stack files to be builded in a common
procedure.

Well the TCP/IP stack needs a small number of files. To me the over head
of using them is worth it.

I do not think this code should be put back into RTEMS as this allows
applications to use interfaces that are not standard to the stack. These
RTEMS extensions may not exists in future ports of the stack as the
filesystem now exists and is stable.

The entries are only read from this table at start up. By the time you
add the extra code to support a C function call API I suspect you will
use more memory than the file will use. Please reconsider using the
file.
