Trying to install SL5.2 i386 via NFS on host CLNT from NFS server SRV.
Server SRV running SL5.1.
Directory on SRV contains SL-52-062608-i386-DVD.iso (integrity verified).

CLNT boots fine using boot.iso CD.
Everything works until after the path of the distribution
directory is specified.  Then failure with "loader received SIGSEGV!".
SRV log shows that the file system is mounted by CLNT.
CLNT running SL5.2 from disk can NFS mount SL distribution
directory from SRV and can mount the DVD.iso file properly.

Had the same problem with SL5.1.  However, SL5.0 worked fine.
Everything works fine with CentOS 5.1 or 5.2
with the distribution on the same file system on the same
host (SRV) and with the same client (CLNT) (so it seems unlikely
that this is an NFS config problem).

With SL5.1 the workaround I used was to copy the .iso file
to a partition on the local disk and install from there.
This worked fine but is a hassle.

The question is what has changed with SL regarding installation
via NFS from SL5.0 to SL5.1, or, alternatively, what is different
regarding installation via NFS between SL5.1 and CentOS 5.1 or
between SL5.2 and CentOS 5.2 ?
