Hi Cris and All.
Looking the source I can find the above code with the same goal.
++++++++++++++++ rtems-ss-20011017\c\src\lib\libc\getpwent.c
++++++++++++++++++++++
static char etc_passwd_initted = 0;
void init_etc_passwd_group(void)
{
FILE *fp;
if ( etc_passwd_initted )
return;
etc_passwd_initted = 1;
(void) mkdir( "/etc", 0777);
/*
* Initialize /etc/passwd
*/
if ((fp = fopen ("/etc/passwd", "w")) == NULL)
return;
fprintf( fp, "root:*:0:0:root,,,,:/:/bin/sh\n"
"rtems:*:1:1:RTEMS Application,,,,:/:/bin/sh\n"
"tty:!:2:2:tty owner,,,,:/:/bin/false\n" );
fclose( fp );
/*
* Initialize /etc/group
*/
if ((fp = fopen ("/etc/group", "w")) == NULL)
return;
fprintf( fp, "root:x:0:root\n"
"rtems:x:1:rtems\n"
"tty:x:2:tty\n" );
fclose( fp );
}

This code has been modified by me in order to add two users and groups.
This code is called always when you call getpwent() the first time.
I suppose that this is a trick done by OAR to give a real behaviour at the
function.
How I need two users ('rtems' a non priviliged user and the dummy 'tty'
owner)
I have added these two lines at the original files.
In the same way two files are very friendly when the user makes a login in
the system.
The /etc/issue & /etc/issue.net

void write_file(char * name,char * content) {
FILE * fd;
fd=fopen(name,"w");
if (fd) {
fwrite(content,1,strlen(content),fd);
fclose(fd);
};
}
void init_issue(void) {
static char issue_inited=FALSE;
struct stat buf;
if (issue_inited) return;
issue_inited=TRUE;
getpwnam("root"); /* dummy call to init /etc dir */
if (stat("/etc/issue",&buf))
write_file("/etc/issue",
"Welcome to @V\\n"
"Login into @S(@L)\\n");
if (stat("/etc/issue.net",&buf))
write_file("/etc/issue.net",
"Welcome to %v\n"
"running on %m\n");
}

In these files the macro expansion are done like Linux.
The /etc/motd is also showed when the file exists after the user login.
Cris.
Is't possible to grown the rtems_init_rootfs in the libmisc/rootfs with this
lines & new files?
Of course removing this duplicate code.
In the same way a /etc/passwd~ shadow password file with the crypt()
function in order to
give certain user login restriction in the ftpd() telnetd() and shell() user
login.
('ssh' is a real goal but too big for the moment)
Several times any users have said to improve the security in the rtems
application
and I think that this is a real need today in all system with tcp/ip with
user
interaction.
BRGDS.
