Debian linux - sysv-rc dependency-based boot system 修復

Debian linux 做 apt-get dist-upgrade, 升級到 sysv-rc 時, 出現下述訊息:

  • sysv-rc

    Unable to migrate to dependency-based boot system
    Tests have determined that problems in the boot system exist which prevent migration to dependency-based
    boot sequencing:
    package exim4-base removed but not purged, package mysql-server-5.0 removed but not purged

    If the reported problem is a local modification, it needs to be fixed manually. If it's a bug in the package, it should be reported to the BTS and fixed in the package.
    See http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot for more information about how to fix the problems preventing migration.
    To reattempt the migration process after the problems have been fixed, run "dpkg-reconfigure sysv-rc".

問題出在 沒有把 exim4-base、mysql-server-5.0 移除乾淨. (移除乾淨要用 apt-get remove --purge exim4-base mysql-server-5.0)
