set of packages required for building
./build/config.<pldistro>/bootcd.pkgs
contents of the bootcd image
-./build/config.<pldistro>/bootstrapfs.pkgs
- the standard contents of the node root
- used to generate yumgroups.xml
-./build/config.<pldistro>/bootstrapfs-*.pkgs
- all *.pkgs files here - produce additional node root images (tar.bz2)
-./build/config.<pldistro>/myplc.pkgs
- contents of the myplc image
-./build/config.<pldistro>/vserver.pkgs
+./build/config.<pldistro>/nodeimage.pkgs
+ the standard contents of the node software
+ this results in a tarball (tar.bz2)
+ also used to generate yumgroups.xml on the plc side
+./build/config.<pldistro>/nodeimage-*.pkgs
+ each of these files results in an extension tarball
+./build/config.<pldistro>/sliceimage.pkgs
the contents of the standard vserver reference image
-./build/config.<pldistro>/vserver-*.pkgs
+./build/config.<pldistro>/sliceimage-*.pkgs
all *.pkgs files here - produce additional vserver images
./build/config.<pldistro>/vtest.pkgs
used to create test vservers for myplc-native
+./build/config.<pldistro>/yumexclude.pkgs
+ describe the set of node packages that are produced by the myplc build
+ and thus should be excluded from the stock fedora repos
+
+=== extensions
+as of this writing extensions are managed as follows:
+- at node installation, the tarball produced from nodeimage.pkgs is
+downloaded and untared to produce the node root filesystem
+- then we attempt to install an extension corresponding to each of the
+extensions that the node has in its 'extensions' tag
+- the first method is to try and download a tarball named after the
+extension. such tarballs are produced by the build from a .pkgs file,
+see above
+- if that fails, then the extension install is attempted through a
+ yum groupinstall extension<nodegroup>
