$ mount /sdc1 FUSE exfat 1.0.1 fusermount: option blkdev is privileged
So I tried as root, and it mounted OK: mount | grep sdc1 /dev/sdc1 on /sdc1 type fuseblk (rw,nosuid,nodev,noexec,relatime,user_id=508,group_id=508,allow_other,blksize=4096)
then as root I tried to copy a file to /sdc1:
# cp rpms.list /sdc1/ cp: cannot create regular file ‘/sdc1/rpms.list’: No such file or directory
So, what else need I do so that regular users can mount and write to usb sticks that are formatted as exfat FS?
These are the relevant rpms installed: fuse-exfat-1.0.1-1.fc20.x86_64 exfat-utils-1.0.1-1.fc20.x86_64

do not have an answer for your question, but i do have a question about what you show above.
you show "/sdc1/" in command, while your 'mount"grep' shows "/dev/sdc1". are you working in "/dev" directory?
with command "# cp rpms.list /sdc1/", is "rpms.list" in current directory?
comment: when showing command lines, is best to 'drag and paste' than just write a command line. sometimes it helps to show full command line prompt.
just asking and trying to understand. :-)

No!! I mount /dev/sdc1 on the directory /sdc1

Current directory (of the shell) happens to be other than /sdc1.

No problem.
I think that there are quirks about the implementation of exfat as a user land driver (filesystem), instead of a kernel driver like ext[n].

No!! I mount /dev/sdc1 on the directory /sdc1
ok. what users/permissions does /sdc1 have set?
as i learned, i have in / path for mounting drives, via fstab or manually, /hdd is owned by root with "drwxr-xr-x.
below /hdd, i have owned by user with "drwxrwxrwx";
/hdd /sda /sdb /sdc /sdd /sde /sdf
below those 6, in each i have: 01, 02, 03, -> 10 ["0x" to keep order] to give all "user"s full read/write/exec permission and no / access.
i still have /media and /mnt available, so program "disk utility" still has access of /media.
with your directory of /sdc1, are permissions correct to allow a user write permission?
as i was taught, giving a user ownership with write and execute permissions to a / directory should not be.
with command "# cp rpms.list /sdc1/", is "rpms.list" in current directory?
Current directory (of the shell) happens to be other than /sdc1.
then err is indicating that ‘rpms.list’ is either not in current directory or user does not have permissions to access file or permissions of target directory are incorrect.

possibly. to verify, maybe changing usb format to 'fat32' and repeating procedure to see if you still get err. if repeats, it is permissions or locations.

I don't know about previous releases as I can only test F22 at the moment.
I would have thought the bigger issue is being able to read/write from the drive for all users which I've been able to do. Are you having any problems now in that area? You seem to have indicated that you did.
If you don't want/can't set the sticky bit, then another option may be install autofs and have the device automounted.
FWIW, if one did some google searching about exfat on linux they'd see that others have asked questions about the ability of non-root users to mount devices in the same manner.
