So = it serves only to provide a root for other var pools (okay) and a number = of /var sub-directories wind up on the root file system (e.g. /var/db, = /var/cache). Is there any specific reason why that choice was made? I working on updating / replacing a 9.0 mfsroot image we use to pxe boot = machines (and decided to pass on 9.3). That image set up /var within = rc.conf (varmfs=3D=E2=80=9CYES=E2=80=9D, populate_var=3D=E2=80=9CYES=E2=80= =9D), but everything there disappears when the machine powers off at the = end of the day =E2=80=A6 and part of my objective is to minimize the = size of root. Mostly curiosity (and my next step it to =E2=80=9Cfix=E2=80=9D = canmount), just thought I=E2=80=99d ask. Oscar=
