Re: Is there a recipe for building and using busybox with libbusybox out there ?

[Phil Blundell <philb@gnu.org>]

Both, really.

If you have several applets running at the same time then they
will/should already share the busybox executable.  I would have expected
making it into a library to increase the memory footprint (as well as
the startup time and image size) since you will now have a bunch of
extra relocs to fix up.
