Suggestion:
Create, or locate a group in /etc/group that you would like to assign
people to have write access to your vfat partitions.
Add yourself to this group.
look at /etc/fstab and modify your vfat partition mount options like so:
/dev/hda1 /mnt/dosc vfat
defaults,user,exec,dev,suid,sgid,uid=0,gid=80,mode=0775,umask=002 0 0
(Line may be wrapped)
You may want to exp. with the umask line, for when trying to untar, or cp
file attributes from ext2 to vat, it will likely complain with the
umask. (It can probably be removed)
Many of the options are opbvious, but the "special ones" important to the
case include te "uid=0,gid=80,mode=775"
What this does is set owner of all vfat files to be root, (assuming root -
uid0) and group owners to be gid of "80" (which I set on my system to be
group "vfat") and then mode 775 sets all of the filesdirs to be rwxrwxr-x,
thought you could choose 770 if you wanted.
This should allow members of group 80 in /etc/grou to write to and read
from your vfat part, and even mount it if it is not mounted.
Hope this helps,
