Re-inserting _*CRITICAL_ critical information from 1st post <begin quote>I have a laptop with multiple installs of Debian Jessie using MATE desktop. There are minor differences of package complements - the purpose being to determine an optimal configuration.
There are a relatively small number of files which I would like to have the latest version available no matter which install is active.

My solution was to place this files on a separate partition of the >>> hdd. It will be mounted at boot. The fstab entry is currently UUID=E90C-65B4 /media/common vfat auto,exec,rw,flush,umask=000 0 0 The problem occurred on the very first use: I opened /media/common by double-clicking its desktop icon. I then: right-clicked on the desktop icon of a text file selected "Copy" from the menu moved mouse over the displayed directory of /media/common right-clicked and chose "Paste" from menu The file was _apparently_ copied as expected. *HOWEVER* the act of copying set the execution flag. Why?I received an almost OFFLIST reply stating: "Because your fstab entry contains the exec directive for the whole filesystem" I suspected something of the sort. The man pages and wiki references were opaque on how to chose the various mask options. What I had expected to happen was for execute flag to be whatever it >> had been set to on the source side. I wanted all users to have rw permission - that was apparently accomplished.The bits are rwxrwxrwx. Setting them all maps to (octal) 777. The umask determines which bits you *don't* want to see set from mount, so umask=111 will strip the execute bits.
That did not work as desired. The files on that partition can *NOT* be deleted.
The *EXPLICIT* purpose is for *EVERYONE* to absolutely free unfettered access to the files on that partition. Think of it as a message board in the local grocery where anyone could post anything. Advertising flyers with tear off phone numbers included.
Alternatively, use a real filesystem that supports permissions better (i.e. at all). vfat is horrid in many, many ways.
This machine doesn't have Windows on it. But I'll want to do the same thing on one with both Linux and Windows.
Ideas?
