Does /etc/motd exist? If yes, what does it contain?

sorry that file doesnot exist in my lfs. do i have to create one?

i think that file is to show message of the day which is shown only after boot.

i need to to change the message before the cheking drivers and all. In kali linux the "welcome to linux!" message is replaced by something like "Kali rolling main" with this red color

at last i figured it out. the message was actually printed by systemd. the message can be changed by editing /src/core/main.c in systemd source

and just recompile the systemd and reinstall grub by grub-install command

the function is given below

int status_welcome(void) {
int r;
_cleanup_free_ char *pretty_name = NULL, *ansi_color = NULL;

r = parse_env_file("/etc/os-release", NEWLINE,
"PRETTY_NAME", &pretty_name,
"ANSI_COLOR", &ansi_color,
NULL);
if (r < 0 && r != -ENOENT)
log_warning("Failed to read /etc/os-release: %s", strerror(-r));

return status_printf(NULL, false, false,
"\nWelcome to \x1B[%sm%s\x1B[0m!\n",
isempty(ansi_color) ? "1" : ansi_color,
isempty(pretty_name) ? "Linux" : pretty_name);
}
