mkjigsnap creates snapshot directories for use by other jigdo tools. It can be run in two distinct modes: Jigit / single-jigdo mode To build a jigit .conf file for a single jigdo file: add the "-n" option with a CD name on the command line and only specify a single jigdo to work with using "-j". Required arguments for this mode: -d snapshot_dir Specify the output directory name to be used for the snapshot tree (e.g. 20041011, rc1). In single-jigdo mode this will be relative to the output directory. -j jigdo_file Specify the location of the jigdo file to be used. -m mirror Specify the location of the mirror containing all the files needed. This must be on the same filesystem as the output directory, as hard links will be used to create the snapshot efficiently. -n CD_name Specify the output name of the CD for jigit (e.g. warty, sarge-i386-1). -o output_directory Specify the output location for the jigdo, template, conf and snapshot. This must be on the same filesystem as the mirror, as hard links will be used to create the snapshot efficiently. -t template_file Specify the location of the template file to be used. Multi-jigdo mode To build a snapshot tree for (potentially multiple) jigdo files: do not specify the "-n" option, and list as many jigdo files as desired, either on the command line using multiple "-j <jigdo>" options or (better) via a file listing them with the "-J" option. Required arguments for this mode: -d snapshot_dir Specify the output directory name to be used for the snapshot tree (e.g. 20041011, rc1). -J jigdo_list Specify the location of a file listing the jigdo files to be used. May be repeated multiple times for multiple list files if desired. -j jigdo_file Specify the location of the jigdo file to be used. May be repeated multiple times for multiple jigdo files, but it's better to use the "-J" option to point at a file containing a list of jigdo files instead. -k keyword Specify the "keywords" which are used in the jigdo files (e.g. Debian, Non-US, Ubuntu). -m mirror Specify the location of the mirror containing all the files needed. This must be on the same filesystem as the snapshot directory, as hard links will be used to create the snapshot efficiently. Options Optional arguments for both modes: -b backref_file If using a fail_log, also keep track of which jigdo files correspond to each missing file, and output the details in the backref_file. -f fail_log If any files are required by the specific jigdo files but are not available in the mirror, list them in the output file fail_log for reference. -i ignore_list If any files are required by the specific jigdo files but are not available in the mirror, list them in the ignore_list file to supress errors about them.
mkjigsnap -o /tmp/mjs-test -n mjs-test -m /tmp/mirror -j ~/jigdo/update/debian-update-3.0r2.01-i386.jigdo -t ~/jigdo/update/debian- update-3.0r2.01-i386.template -k Debian -k Non-US -d 20041017 This command is an example of single-jigdo mode, used for Ubuntu jigit generation. It creates a single jigit conf file using the supplied jigdo/template file pair, looking for jigdo references to files in the "Debian" and "Non-US" areas. Output the files into /tmp/mjs-test and call them "mjs-test.<ext>", creating a snapshot of the needed files in /tmp/mjs-test/20041017 by linking files from /tmp/mirror as needed. mkjigsnap -m /org/ftp/debian -J ~/jigdo.list -k Debian -d /org/jigdo-area/snapshot/Debian -f ~/mkjigsnap-failed.log -i ~/mkjigsnap- ignore.list This command is an example of multi-jigdo mode, as run to keep http://us.cdimage.debian.org/cdimage/snapshot/ up to date. This reads in all the jigdo files listed in ~/jigdo.list, building a list of all the files referenced in the "Debian" area. It will then attempt to build a snapshot tree of all those files under /org/jigdo-area/snapshot/Debian by linking from /org/ftp/debian. Any files that are missing will be listed into the output "missing" file ~/mkjigsnap- failed.log for later checking, UNLESS they are already listed in the "ignore" file ~/mkjigsnap-ignore.list.
