I originally had an Xubuntu 14.04 (32 bit) on my machine. I have now also installed a Ubuntu 14.04 (64 bit) on the same machine and plan to migrate eventually there. In both OSes I have access to files belonging to the other OS.
If I edit a file belonging to Xubuntu while I am on the new OS, or the other way around, would the other OS think the FS is corrupt once I boot it up? The files are mostly php, css, js, html files and nothing fancy/crazy.
