To build a complete openslug flash image:

        oemake openslug-image (assuming you are building openslug)

To push up all new changesets to parent:

        bk parent nslu2-linux@nslu2-linux.bkbits.net:packages (to use SSH, which requires write access)

To receive and apply a changeset received by mail:

        bk receive < <changeset email file>
        bk resolve

Note that this page uses building OpenSlug.HomePage OpenSlug? as the worked example, whereas the GettingStarted guide uses building Unslung.HomePage Unslung? the worked example. Hence the two pages differ for a good reason.

                             it shows diffs of all files against the repo but is horribly slow)

        bk citool

To create a changeset: (command-line)

        bk ci <each modified file>
        bk add <each new file>
        bk commit -y"comments"

To send a changeset to mailing list for peer review:

To review changesets:

        bk csets

Revision Tool:

        bk revtool (then open the file in question)

Creating a patch:

        diff -urNd oldtree/ newtree/ > patch

Add a patch to a package:

        add a "file://blahblah.patch;patch=1" entry to the package's SRC_URI.

Listing locally modified files:

        bk sfiles -c shows local modifications (as does bk -r diffs -u, since it shows
                diffs of all files against the repo but is horribly slow)
        bk sfiles -pC (and bk pending) shows changes that have been checked
                in, but not yet included in a changeset
        bk sfiles -x shows files that are in the repository but not yet
                controlled by bk (handy to make sure you didnt forget to bk add all the patches from a build)
        bk sfiles -c | bk diffs -u -

        oebuild showdata <path_to_package_oe_file> | grep PN.*=

Forcing a package to retrieve a specific snapshot:

        Add "CVSDATE_<package_name> = <YYYYMMDD>" to the appropriate configuration file (ex: conf/local.conf)

Flashing final image to NSLU2 using Redboot (requires serial access):

        splitnslu unpack <oe produced bootstrap image from /deploy/images/>
        ip_address -l 192.168.2.77 -h 192.168.2.1
