Because if I don't I keep getting this annoying popup saying to update, and if I choose the option to hide it it just comes back on next boot. It is something to do with the system making a fresh new superboot folder on each boot in the root of the device, thus resetting everything. I may just go back to non root for now as it's massively irritating.
Why do you "have" to update the superuser...? Unless you have it on auto update then that should not apply. As I have not used this for the Skate (I use a custom ROM) I would not know if the latest SU causes issues with the Skate when and if the binaries are updated from the market. It used to cause a problem with people losing root access with the blade during one of the SU updates, when the binaries were updated.
Mine is using version 3.0.7 (41) and looking at the log everything which requires SU access has been granted and remains so when rebooted.
EDIT: Fixed it by re-flashing the stock boot.img from the unbranded 2.3.5 ROM I am using, now no more legacy superboot folder creation on boot, yet root and all values/permissions have been kept.
This device is making me learn new things fast .
