13 At a low level, only swap can't be shared 100% due to suspend to disk.
14 If you are not using suspend to disk, then you can share swap without
15 any problems. But if you suspend one OS and then boot into the other,
16 the suspend data is going to be corrupted. At best you'll crash when
17 trying to resume, at worst you'll resume OK but will get corrupted data.
19 At the OS level, /home can be shared without problems. At the
20 application level (and I'm talking about KDE, Gnome and other DEs here),
21 you could get bugs or weird behavior due to using different versions of
22 the same DE.
