I have some feed back and this may be directly related to me since I use smartcoin

-1) I noticed that the prefinal version of linuxcoin does not cleanly reboot ( could be an issue for remote administration
-2) may want to make the final default persistent boot option
-3) for some reason I have to run my aticonfig commands as root now where that wasn't needed on the .2b version ( causes issues with smartcoin)
-4) the packaged install of smartcoin does not work ( may be easier to just include a install script that will install the latest version if the end user would like to utilize it )
+5) it does boot faster
+6) I like the secure bitcoin client ( even though I dont use a local wallet )

This is just what I have noticed when playing with it in the last 30 min may have more later
