Chanko, short for chanko-nabe, is a stew (a type of nabemono or one-pot dish) commonly eaten in vast quantity by sumo wrestlers as part of a weight gain diet.
Chanko initially leveraged a project called sumo for caching and sharing the public data sets (hence the name - chanko feeds sumo), but has since dropped it's dependency of sumo, but the name has stuck.
Chanko has 5 commands:
get - Get package(s) and their dependencies
upgrade - Upgrade packages according to plan
purge - Purge superseded packages
refresh - Refresh the index files and cache
query - Query the chankoRefer to the commands help for more information, for example:
chanko-get --help.internal/ - created automatically, used internally
archives/ - created automatically, stores downloaded packages
config/ - configuration folder, see below
plan/ - create automatically, see belowA chanko requires 3 files stored in the sub-folder config/
For example:
$ cat config/sources.list
deb http://cdn.debian.net/debian squeeze main
deb http://security.debian.org/ squeeze/updates main
$ gpg --keyring ./config/trustedkeys.gpg --list-keys

$ cat config/chanko.conf
RELEASE=debian/squeeze
PLAN_CPP=-DFOO=yPlans are stored in the plans sub-folder. A plan can be named anything but there are 2 'special' plan names:
- plan/main - new packages added to the chanko with chanko-get
will be appended to this plan by default.
- plan/nodeps - if the --no-deps flag is specified with
chanko-get, new packages will be appended here.
When chanko-upgrade is executed, the packages
specified in this plan will not pull dependencies.Due to the nature of chanko, there might be instances where packages conflict with one another, in which case chanko-upgrade will fail. In this case, another plan should be used to specify one of the conflicting packages.
Plans are processed through cpp which give plans some intelligence, as well as support for cpp comments. Automatically, the architecture and plan folder will be specified as additional cpp_opts.
For example:
#ifdef FOO
#include <include/foo>
#endif
#ifdef I386
linux-image-686
#endif
#ifdef AMD64
linux-image-amd64
