Just tried it, apologies if that has already been reported (i'd think it probably has, so just in case)
- booting from usb specifiying home= blkid does not work; in fact after booting i cannot see my flash drive anymore at all
- the cursor disappears on tabs of Chrome (i have seen that happening in other areas of midori or qtweb
Beside this is looks very promising, compared to the issues i have had wih 4.0 on my laptop.
Also I noticed the ethernet is 2x as fast as with 4.0. Have not tried wifi yet as it needs a non-included driver.
