LABEL 대신 디바이스 이름을 직접 입력해 보세요. 예를 들어
LABEL=/usr 를 /dev/sda3 로 고침/

스왑파티션이 없는것 자체가 이상하군요. 이 문제
확인해보세요.
/dev/sda6 가 혹시 스왑?

/var 디렉토리 구조.

cache  db  empty  lib  local  lock  log  mail->spool/mail  nis  opt  preserve  run 
spool  tmp  www  yp

퍼미션은 모두 755 이고, /var/tmp 은 1777(drwxrwxrwt)

시간이 된다면 다른 서버의 RH9 /var 구조를 그때로 따라서
디렉토리를 만들어 보세요.

이렇게 옵션이 끝났다는 의미의 하이픈 두개(--)를 넣어주고
지워보세요.
