너는 뭐냐?

busybox~~

~~

비즈박스는 뭐죠?

대대체...비즈박스만 나와요..

심지어 init도..

exe의 경로는

/bin/busybox

로만 나옵니다..

왜그러는거죠?


# pwd

/proc/1

# ls -la exe

lrwxrwxrwx    1 root     root             0 Dec 15 05:39 exe -> /bin/busybox




음...

그래서 /sbin/init의

실체를 확인해보았습니다.


# ls -la /sbin/init

lrwxrwxrwx  1 root   root        14 Dec  4 08:44 /sbin/init -> ../bin/busybox


아니 이런;;;

/sbin/init은~~

‘../bin/busybox’

의 링크였군요~~!!

이런 이런

심지어

모든 파일이 다...

busybox에 링크되어 있었습니다.

# cd /bin

# ls -la
