Can't import keys -- link() failed

[Sam Sanjabi]

Hi folks,

I just started using gnupg a couple of weeks ago.  The other day, I tried
to import a key that I got off of kernel.org using

	gnupg --import kernel.org.pub

but I get the following error message:

[sam@sam linux-2.4.3]$ gpg --import kernel.org.pub 
gpg: lock not made: link() failed: Operation not permitted
gpg: fatal: can't lock `/mnt/floppy/.gnupg/pubring.gpg'
secmem usage: 1408/1408 bytes in 2/2 blocks of pool 1408/16384

As you can see, I have stored my key rings on floppy disk.  It is not
write protected, and I have the correct permissions.  In fact, I
successfully imported and signed another key a week ago.

My GNUPGHOME environment variable is set to /mnt/floppy/.gnupg/

There are no lock files in that directory.

I can't even successfully export and re-import my own key without getting
this message anymore.

I've scoured the FAQ and this mailing list's archive to no avail, can
anyone help me?

Thanks,
Sam Sanjabi.
