vmlinux 란? 리눅스 커널을 한 번이라도 빌드한 경험이 있다면 vmlinux와 vmlinuz라는 파일을 본 경험이 있을 것입니다. 빌드 경험이 없더라도, 리눅스 루트 파일시스템을 돌아다니다가 /boot 디렉토리 내에 있는 vmlinuz 혹은 bzImage를 보았을 수도 있고요. 이번 글에서는 위 파일들이 무엇이며, 어떤 역할을 하는지 한 번 알아보도록 하겠습니다. vmlinux 우선 리눅스 커널은 다른 프로그램과 마찬가지로 하나의 실행 가능한 프로그램입니다. gcc를 통해 c언어 소스코드 main.c를 빌드했을 때 a.out 이름의 ELF 바이너리가 나오는 것 처럼 커널도 빌드하면 ELF 바이너리가 나오게 됩니다. 그리고 이 바이너리가 vmlinux입니다. ...
