Default [Q] Will Acer Iconia Toolkit root an A1-810 running 4.2.2 (RV31RC03_WW_GEN1)?

My A1-810 is stock/unrooted, but I've done the interim update to 4.2.2 that came out recently. However, I've decided NOT to go to KitKat until I'm sure it can be rooted and I just want to root my tablet now, but I'm unsure of how to proceed.

My image version is now RV31RC03_WW_GEN1, but there's no corresponding downloadable pre-rooted image on the main XDA Toolkit page. Since I would like to root from scratch in Linux, I wouldn't think this would be a problem, but I'm not sure.

Does anyone know what I should do? It seems like it should work fine, but don't want to brick my tablet. Thanks...
