Thank you for answering.

But this solution won't work well if I use link=static from command
line, which is frequently used for local builds to avoid installing
needed boost version system wide. Is there any way to say that library
should be linked "default" way, i.e. stop this requirement from
propagating?

Also bjam seems to rejects this entirely:

....
lib my_lib
:
  lib.cxx
:
  <use>/boost//system <link>shared
  <link>static
;
....

# bjam -d
explicitly-specified values of non-free feature <link> conflict

Thanks.
