These messages come from new_init_action() routine, and it is called here
in init.c, parse_inittab():
for (a = actions; a[0]; a += strlen(a) + 1) {
if (strcmp(a + 1, action + 1) == 0) {
*runlev = '\0';
if (*id != '\0') {
if (strncmp(id, "/dev/", 5) == 0)
id += 5;
strcpy(tmpConsole, "/dev/");
safe_strncpy(tmpConsole + 5, id,
sizeof(tmpConsole) - 5);
id = tmpConsole;
}
======> new_init_action((uint8_t)a[0], command + 1, id);
goto next_line;
}
}
*command = ':';
/* Choke on an unknown action */
bad_entry:
message(L_LOG | L_CONSOLE, "Bad inittab entry: %s", id);
next_line: ;
}
fclose(file);
}
(Calls to new_init_action() elsewhere would not trigger for you I think).
Apparently init segfaults somewhere after this.
Can you add these debug prints in the above code fragment
and tell us what do you see?
for (a = actions; a[0]; a += strlen(a) + 1) {
if (strcmp(a + 1, action + 1) == 0) {
*runlev = '\0';
if (*id != '\0') {
if (strncmp(id, "/dev/", 5) == 0)
id += 5;
strcpy(tmpConsole, "/dev/");
safe_strncpy(tmpConsole + 5, id,
sizeof(tmpConsole) - 5);
id = tmpConsole;
}
bb_error_msg("before new_init_action");
new_init_action((uint8_t)a[0], command + 1, id);
bb_error_msg("after new_init_action");
goto next_line;
}
}
*command = ':';
/* Choke on an unknown action */
bad_entry:
message(L_LOG | L_CONSOLE, "Bad inittab entry: %s", id);
next_line: ;
}
bb_error_msg("finished parsing iniitab");
fclose(file);
}
