[Matthew Dillon]

:Hi !
:
:Would you please consider this ?
:Any commects on style and functionality are welcome.

:I'm rather unpleased by unconditionally returning
:RC_CONFIGURED in savecore, but I couldn't come up with an
:idea how to *check* it like I could with swap1.

    Committed with minor changes... your df_swap1_start() routine 
    was broken.  It needed to backtick the sysctl command and use
    SYSCTL_N rather then SYSCTL, and the conditional was reversed.
