I tried asking this on the forum, didn't get any real answers, so I'm hoping someone here can help.
I have a script located on a Vfat-formatted flash drive. When mounted using udisks, there are no execute permissions showing on the files, and they cannot be set.
After some research, it seems that udisks works with polkit to set things like permission on mounted devices. Unfortunately, so far my attempts at research haven't led me to any information on setting permissions the way I need them, or even where the settings are stored. So I'm hoping someone can point me in the right direction - I want to be able to modify things like execute permissions on mounted devices when I need to. I'm not all that partial to being effectively told I can't do that - reminds me much too much of Windows.
I've tried a few workarounds, with little or no success. I installed pmount and used it with the -e option to mount the device. Still no execute permissions. I tried using sh to execute the script - failed again.... I also tried adding the device to /etc/fstab. In that instance, the file showed as executable, but any attempt to execute it, even as root, got a 'permission denied' message. Argh!

Have you tried manually mounting with something like: # mount -o exec /dev/whatever /mount/point I don't use udisks, but I use pmount and (I think) it automatically mounts with the noexec option. I have never had a reason to try to get around this, so I also cannot speak to whether or not working around it is functional. But I figure if you do it manually, and specify exec, if it still doesn't work, then you at least then know that it is not specific to any of these automounting functions you use. -- Curtis Shimamoto sugar.and.scruffy@gmail.com
