=== linuxrc ===
* linuxrc 는 sbin/init 에 link 되어 있음
* sbin 밑의 halt, poweroff, shutdown 은 init 에 link 되어 있음.
* linux rescue 의 경우 이외에 사용가능한가?
* anaconda/loader2/init.c 가 source 임
* /proc, /dev/pts, /sys 를 마운트
* console(/dev/console) 에 해당하는 것을 찾아 device 에 assign.
* 호스트명 설정 localhost.localdomain
* / 파일시스템을 r/w 로 다시 마운트 (어떻게 마운트를 할까?)
mount("/", "/", "ext2", MS_REMOUNT | MS_MGC_VAL, NULL)

=== loader ===
* insmod, modprobe, rmmod 가 loader 에 link 되어 있음.
* linux rescue 이외의 경우에 사용가능한가?
* anaconda/loader2/load.c 가 source 임.
* insmod, modprobe, rmmod 는 modstubs.c 에 있음.
* 옵션 점검 및 설정 cmdline, ksfile, test, mediacheck, virtpconsole
* 모듈관련 작업
* /modules/module-info 를 읽어 modinfo 에 저장
* /proc/modules 를 읽어 modloaded 에 저장
* /modules/modules.dep 을 읽어 modDeps 에 저장
* console 을 위한 모듈, font, keymap 을 올림.

* firewire 초기화
* firewire controller 이 있는지 점검
* 있으면 관련 모듈 로드
* read /modules/pcitable
* language set (loader 의 언어)
* cmdline 에 입력된 모듈 로드
* 디바이스 검색 (probeDevices)

* selinux 관련 작업
* 다시 모듈을 올리는 작업을 함. (kickstart 때문인듯함)

=== anaconda ===
boot 옵션으로 줄 수 있는 것은 하드웨어 검색 disable, 인스톨 미디어 시험, 인스톨 방법 선택 등이 있슴.
http://www.cwelug.org/cgi-bin/wiki.cgi?FedoraCore3
anaconda 를 분석하지만, live CD 를 만드는데 필요한 부분만 분석합니다.
/sbin/loader 가 옵션을 추가하여 anaconda 를 call 하는듯함.

anaconda 에서 메뉴 화면 디스플레이하고 setting 하는듯함.
