[64studio-devel] HDD: Write permissions for ordinary

[Michael Pacey]

Hi,

I'm using DeMuDi on this machine but this should apply to 64 Studio too.

The permissions of the device files are managed through the
file /etc/udev/permissions.rules

My user account is mpacey and I am in the group mpacey as seen from the
output of the id command:

uid=1000(mpacey) gid=1000(mpacey)
groups=7(lp),20(dialout),24(cdrom),25(floppy),29(audio),44(video),46(plugdev),106(camera),107(scanner),1000(mpacey)


I have a FAT filesystem on /dev/hda3. To make the device file read/write
to me, I added the following line to /etc/udev/permissions.rules:

KERNEL=="hda3",                                 GROUP="mpacey"

I added it near the end, so it overwrites the default GROUP applied to
BLOCK devices (disk).

I created a mount point (as root): mkdir /mnt/hda3

To make it mountable by a normal user, I added the following
to /etc/fstab:

/dev/hda3       /mnt/hda3       vfat    noauto,defaults,user 0 0

To get this mounted automatically on startup, I changed this to:

/dev/hda3       /mnt/hda3       vfat    auto,defaults,user,uid=1000 0 0

1000 is my UID, yours is probably 500, id will tell you.

So if you know the /dev/ names of your FAT32 filesystems, then make
suitable mount points, add suitable lines in /etc/udev/permissions.rules
and add suitable /etc/fstab entries like I have shown.

Hope this helps!
