Exporting fs from a looped squashfs in linux

Hi,

I'm trying to serve a mounted loop-filesystem (squashfs) from a linux
box to other unixes. And it doesn't work due to (I think) something
related to /proc/fs/nfs/filehandle.

The server, on mount, says only (mountd with -d all)
Nov  4 23:05:11 llimona rpc.mountd: MNT3(/nfs/sparc/netbsd/usr/) called
Nov  4 23:05:11 llimona rpc.mountd: authenticated mount request from
mandarina:872 for /nfs/sparc/netbsd/usr (/nfs/sparc/netbsd/usr)

The client, on mount says only:
mount: llimona:/nfs/sparc/netbsd/usr/ failed, reason given by server:
S'ha denegat el permís
(That is, Permission Denied)

I've straced a foreground rpc.mountd, and I've seen the next:
open("/proc/fs/nfs/filehandle", O_RDWR) = 9
fstat64(9, {st_mode=S_IFREG|0600, st_size=0, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xb7efd000
write(9, "* /nfs/sparc/netbsd/usr 64 \n", 28) = -1 EPERM (Operation not
permitted)
read(9, "", 4096)                       = 0
close(9)                                = 0
munmap(0xb7efd000, 4096)                = 0
sendmsg(6, {msg_name(16)={sa_family=AF_INET, sin_port=htons(872),
sin_addr=inet_addr("192.168.1.33")},
msg_iov(1)=[{"\36\201\"\21\0\0\0\1\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"...,
28}], msg_controllen=24, msg_control=0x805ce38, , msg_flags=0}, 0) = 28

So you can see the "EPERM" related to the 'filehandle' proc file. What's
happening here? Am I unable to export a loop squashfs?

Thanks in advance!
