  We construct rolling tachyon solutions of open and boundary string field
theory (OSFT and BSFT, respectively), in the bosonic and supersymmetric (susy)
case. The wildly oscillating solution of susy OSFT is recovered, together with
a family of time-dependent BSFT solutions for the bosonic and susy string.
These are parametrized by an arbitrary constant r involved in solving the Green
equation of the target fields. When r=0 we recover previous results in BSFT,
whereas for r attaining the value predicted by OSFT it is shown that the
bosonic OSFT solution is the derivative of the boundary one; in the
supersymmetric case the relation between the two solutions is more complicated.
This technical correspondence sheds some light on the nature of wild
oscillations, which appear in both theories whenever r>0.
