The slackware-upgrade-system will be +installed to /sbin, and its man page, slackware-upgrade-system.8, to +/usr/man/man8. These are most suitable locations for Slackware. To +install them elsewhere, use the following Makefile variables: + + SBINDIR - Directory to install slackware-upgrade-system to. + MANDIR - toplevel directory for man page installation (/usr/man). + MAN8DIR - directory for the man page installation ($(MANDIR)/man8). + +Usage +===== + +Before upgrade, please make sure you backup all sensitive data on your +system. When upgrading a remote machine, it advisable to have a KVM +console attached to it, so that you can intervene if the box refuses +to boot. + +Please read slackware-upgrade-system(8) to familiarize yourself with +the script and its options. + +Run slackware-upgrade-system in dry-run mode: + + slackware-upgrade-system -n + +This will look for the nearest next release available, create the list +of packages to be upgraded, installed and removed and will print the +results. This run will not touch any files on your filesystem +(excepting the slackware-upgrade-system logs, see below). Instead it +will verbosely print what would have been done during real upgrade. +Inspect its output to see if it actually does what you need. In +particular, the upgrade will most likely decide to remove some +packages during the upgrade. These are the packages that existed in +your current release, but have been removed in the next one, or the +packages you have installed from third-party sources. You may wish to +retain any of them or provide replacements, or reinstall them afterward. + +If you wish to retain any of them, create a list of packages to retain +and supply it to the script using the -k command line option (see the +man page for details). + +To provide a replacement, use the -p option. For example, when +upgrading from 14.1 to 14.2, the "procps" package will be removed. The +utilities it used to provide have been moved to the "procps-ng" +package. So, when upgrading from 14.1 to 14.2, it is a good idea to +use + + slackware-upgrade-system -p procps-ng + +For your information, the list of removed packages is left in file +/var/log/slackware-upgrade-system-<P>-<N>.removed (see below). + +When you are finished with the dry run, proceed to the actual upgrade. +Run + + slackware-upgrade-system + +with any additional options you decided to give it after the dry run. +After completion, the script will create three files for your +consideration. In the discussion below, <P> stands for the original +Slackware version number, and <N> stands for the new Slackware version +number (the version you upgraded to): + +/var/log/slackware-upgrade-system-<P>-<N>.log + Log file. Contains detailed transcript of all actions performed + during the upgrade. + +/var/log/slackware-upgrade-system-<P>-<N>.removed + A list of packages removed during the upgrade. A package is removed + if the new release does not provide a replacement for it. This may + not always be desirable, and you may reinstall some of them + afterward. + +/var/log/slackware-upgrade-system-<P>-<N>.conffiles + A list of configuration file replacements created during the upgrade. + These are configuration files provided by the upgraded packages that + are left in the filesystem along with your current file versions. + They have the same names as the original files, but with the ".new" + suffix. Please revise these files. You may need to merge them with + your actual files, or move them over, or simply remove them. + +Before attempting to reboot your system, please make sure that the +bootloader has been updated for the new kernel. + +Special notes +============= + +We recommend to always upgrade to the next release, without skipping +release numbers (even though the script allows you to do so). For +example, instead of upgrading from 14.0 to 14.2, run two subsequent +upgrades. First, upgrade your system, to 14.1 and make sure everything +works as expected. Then, upgrade it to 14.2. + +License +======= +This program is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 3, or (at your option) +any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
