I guess by "basic rootfs" you refer to the core-image-basic image?
Well, the "basic" in the name really means what it says: this is a
root file system which contains just the very basic tools needed to
run a system.  Package management is not considered such a basic tool,
so it is not included here.  And without a package database you cannot
get any package information.

Ditto - there is simply no information there that could be listed.

This depends which type of init system you install in your root file
system.  For example, the core-image-basic image uses a SystemV style
init, so to start a service you would use "sh /etc/init.d/<name> start";
to enable the service for a specific runlevel you would create a S*
symlink in the respective /etc/rcX.d/ directory (i. e. do manually
what "chkconfig" resp. "service" would do).

Both "chkconfig" and "service" are very simple tools.  "chkconfig" is
part of the chkconfig package; if you want it included with your root
file system, you can add the chkconfig recipy to your machine
configuration.  "service" is but a shell script...
