I have a weird problem when mounting a fat32 partition in my recently installed gentoo. When I mount it, the folder /mnt/hd changes automatically its permissions and it becomes executable only by owner (root). Other users can read, but no execute, so they cant access the partition. I have tried all possible options in fstab, user, exec, users, umask=0000, 0002, 0222, but it is the same.
Can somebody give me an idea about how to solve this?

This is because you are mounting a file system over the existing directory and takes on the permissions given by the mount command.

The fat32 file system has no idea of file permissions, so all files are owned by the user mounting it (fstab = root).

There are a couple of ways to overcome this:

1) add a new group called 'fat32' and add the people that you want to have write permissions to the group; then add gid=fat32 to the options for the mount in fstab.

2) add the 'rw' option to the fstab entry.


If I'm right, the umask option are not applicable for fat32. See 'man mount' for details of options for each fs.
