DESCRIPTION

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.

EXAMPLES

       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.
