We've reviewed the SDF system prior today's scheduled fast front-end reboot. We've only accepted things we can confirm we know are necessary because of physical changes to the IFO. Otherwise, we reverted to the safe values and/or left things as DIFFs (because the reboot will revert).

Kissel, Vo (ISC / SUS / IMC)
    - Accepted outputs and offsets on for all SUS by putting them in the ALIGNED state (i.e. when all OUTPUT switches are ON; a few new or neglected SUS needed this, like RMs, ZMs, OFI OPO), because the watchdog protects the system upon reboot.
    - Accepted a few new misalignment offset values (SRM, ITMs, PRM) because we've physically changed the alignment of these suspensions during the Sep-Dec 2017 corner vent, and the misaligned position has now been confirmed by a few months worth of corner station commissioning
    - SR3 optical lever input gains to ZERO until we make the front-end changes need to get it up and running (see LHO aLOG 41547)
    - In ISC land, accepted dark offsets on AS A & B and OMC QPD (remeasured to make stuff work in air, will likely have to be remeasured in the future anyways)
    - 180 phase change in ASC OMC DC centering loops because of the tip-tilt actuator sign flip (LHO aLOG 41441)
Radkins (SEI)
    - Cleared out by Hugh -- most diffs are because some chambers are locked, and/or the sensor correction configuration is OFF which is "abnormal" for observing
Bartlett, King (PSL)
    - FSS and PMC are stable, so J. Bartlett & P. King accepted the DIFFs on this.
    - ISS and DBB 

We're OK to Go for reboot of front-ends.
