It seems impossible to make lufs (lufs-0.9.7) on 64 bit arch (Linux asus 2.6.10 #1 Thu Jan 27 22:46:08 EST 2005 x86_64 x86_64 x86_64 GNU/Linux).

(btw, this is all in an attempt to NTFS writable... no matter what I do I get permission denied... 1) ntfs RW compiled into kernerl, mounted with umode=0 and mount point mode 777)

After some searching I fond a related gnet issue on 64 bit, with a response from someone who has fixed the problem.

I've attached a patch I will push if it works for you. What it does is
generate the xdr routines in the autofsng build instead of trying to
link in librpcsvc.

The problem you are seeing is probably due to that bit of glibc not
being compiled with -fPIC, which means the .a in question can't be
linked into a .so on x86-64.

Another heads up for trying out autofsng on x86-64: I haven't yet added
the system call table entry for sys_mountfd. If anyone gets to it
before I do, patches are welcome
