I have posted an update to UberBang on the same SourceForge project page. It now includes the FBXKB keyboard layout switcher system tray icon, and Volumeicon and NM-Applet are now fully functional. Also present are the Openbox, GTK, and icon themes from the latest build of #! 10 "Statler"; however, the default GNOME-Colors-Statler icon theme used seems to not have been copied over correctly, as some icons (e.g. back, forward) appear a little weird. It seems like Elementary-Statler works fine though. Maybe for the next update I'll use that instead.
I read on the #! forums of people trying UberBang and being able to successfully use the live session but not being able to properly install it. With the previous releases I didn't have the time to look into these further; now I have the time, and I can confirm that UberBang doesn't install properly. It seems to be a known problem with Remastersys, but looking on the Remastersys forum didn't yield a whole lot of useful information (I tried one thing, but it led to a segmentation fault (another error type)). If anyone reading this has used and is familiar with Remastersys, please let me know what I should be doing so that UberBang can actually be installed.
In unrelated news, before coming to the Blogger Dashboard page, I often read news on various other tech sites including (but not limited to) TechDirt, Linux Today, Raiden's Realm, and Tech Drive-in. Having done that a couple minutes ago, I would like to let readers know that Raiden's Realm has been hacked; all that's present is scrolling mixed Arabic/English text on a black background.
