I feel like answering RTFM again, but you've been reasonable and polite. Thank you for your courtesy.
'apt-get upgrade' is restricted (and therefore safer) in that: under no circumstances are currently installed packages removed, Neither the apt-get nor the aptitude man page make that distinction (which is not to say it's wrong, just that you can't learn it by RingTFM). The apt-get man page distinguishes upgrade from dist-upgrade only by noting that dist-upgrade is smarter than upgrade about resolving conflicts. It may be that dist-upgrade smartly resolves conflicts by removing currently installed packages, but the man page doesn't explicitly indicate that. The aptitude man page doesn't, except for the synopsis, mention dist-upgrade at all. As an aside, the apt-get and aptitude man pages describe different behaviors for upgrade. For apt-get, upgrade has the non-removal behavior described above. For aptitude, the upgrade behavior is "Installed packages will not be removed unless they are unused". This is on a debian testing system, upgraded once a week. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
