>Description:

The problem surfaces itself eg. when doing cvs co on the client. The client
used to panic, but panicing was fixed by Frank van der Linden. One
thing remains: directories. You must recognize directories. Then, only then
will exporting lfs work:

babylon5:22:/sources> cvs co pkgsrc
cvs server: Updating pkgsrc
U pkgsrc/Makefile
cvs [checkout aborted]: writing pkgsrc/Packages.txt: Input/output error
Write failed flushing stdout buffer.
write stdout: Broken pipe

and then:
babylon5:57:/sources/pkgsrc> ls -ld .new.Packages.
drwxr-xr-x  1 pooka  wheel  0 Nov 17 10:32 .new.Packages.
babylon5:58:/sources/pkgsrc> file !$
file .new.Packages.
.new.Packages.: directory
babylon5:59:/sources/pkgsrc> rmdir !$
rmdir .new.Packages.
rmdir: .new.Packages.: Not a directory

but on the server:
dungeonmaster:7:/m/dm/sources/pkgsrc> ls -l .new.Packages. 
-rwxr-xr-x  1 pooka  wheel  0 Nov 17 10:32 .new.Packages.
dungeonmaster:8:/m/dm/sources/pkgsrc> file !$
file .new.Packages.
.new.Packages.: empty

Here's a tcpdump of what's happening (not from the above checkout, but
something done earlier):

The disklabel on the server look like this:
#        size   offset     fstype   [fsize bsize   cpg]
  a:  6185088        0     4.4LFS     1024  8192     0   # (Cyl.    0 - 6135)

The only extra parameters give to mount are -b and -i.
