During the early days of Linux, UMSDOSfs was a quite useful tool, being able to superimpose UNIX file names and ACLs on top of a vanilla FAT filesystem.
With devices that might need to restrict access, but still require FAT32 because of interoperability concerns, would a variant of UMSDOS that works on this filesystem ever be feasible? Take Android for instance. The only way to keep app "A" and app "B" separated when they are granted access to an external SD card is by using SELinux rules (which the default pretty much denies access.) Having the ability to enforce permissions while still preserving interoperability of SD cards would be very useful.
Would it be possible to see UMSDOSfs return? (Score:3)
