you're probably removing too many packages, eg some key package is a dep 
of MINIMAL but not in MINIMAL, and "yum remove" removes it and all its 
Maybe add "yum install $MINIMAL" after your yum remove command.
Or replace yum remove with "rpm -e" to see if and who in $SUPPRIMER has 
deps in MINIMAL.
