[질문]부팅 중 Freeing unused Kernel Memory 멈춤현상??

VFS : Mounted root readonly
Freeing unused Kernel Memory : 64k freed

안녕하세요??

x86에 20메가 짜리 root파일 시스템을 구축 할려고

호스트(컴파일용 데스크탑)에 레드헷 7.3을 깔고,

타겟(임베디드 보드)에 파티션, 파일시스템 생성 을 했습니다.

참고로 SysV init 2.84, busybox-0.60.3,tinylogin-1.02를 컴파일 해서 올렸구요

그리고 커널 ( kernel-2.4.18 ) 설정 대략 맞추고 나서 커널 올리고 lilo실행 하고 난뒤

부팅 할때 위와 같은 메시지를 뿌리더니

멈추더군요.

물론 요 다음은 init를 실행하죠

흠 .. 가만히 생각 해보니 init가 없을때 나오는 메시지가 아니더라구요. 그렇다고 inittab이 없는 것도 아니구요.

커널 소스에 디버그 메시지 넣어서 추적(?)하니깐

다음 명령을 실행 한뒤 멈추더군요.

kernel-dir/init/main.c ->
 execve("/sbin/init",argv_init,envp_init); 

여러분의 조언을 기다립니다.

다음은 inittab의 내용입니다.

# Default runlevel. The runlevels used by RHS are:

#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
#   3 - Full multiuser mode
#   4 - unused
#   5 - X11
#   6 - reboot (Do NOT set initdefault to this)
