+======================================== bootstrapfs
+right now, the actual name of the bootstrapfs('s) that need to be installed is performed in
+the InstallBootstrapFS step
+the logic is
+
+* if the node has the 'deployment' tag set, then we fetch
+https://.../boot/bootstrafs-<deployment>.tar.bz2
+
+* other wise we get
+https://.../boot/bootstrafs-<node-family>.tar.bz2
+ plus
+https://.../boot/bootstrafs-<extension>-<arch>.tar.bz2
+ for all defined extensions
