Thanks for that.

I actually just tested this using a real Red Hat Enterprise Linux 5.6
machine and it works.  Can you try the following commands.  For your
reference the output from RHEL 5.6 is shown.

$ ls {,/usr}{/lib,/lib64}/libz.so*
ls: /lib/libz.so*: No such file or directory
ls: /lib64/libz.so*: No such file or directory
/usr/lib64/libz.so    /usr/lib64/libz.so.1.2.3  /usr/lib/libz.so.1
/usr/lib64/libz.so.1  /usr/lib/libz.so          /usr/lib/libz.so.1.2.3

$ grep libz /usr/lib64/guestfs/initramfs.epel-5.x86_64.supermin.hostfiles 

$ rpm -qa --qf '%{name} %{version} %{arch}\n' | grep zlib
zlib 1.2.3 x86_64
zlib 1.2.3 i386
zlib-devel 1.2.3 x86_64
zlib-devel 1.2.3 i386

Comment 6 Javier Fdez. Landa 2011-10-24 14:17:15 UTC
Here are the output of the same commands plus others from my CentOS 5.7. There are new libz libraries in /lib and /lib64 directories.

[root@nim1 ~]# ls {,/usr}{/lib,/lib64}/libz.so*
/lib64/libz.so.1      /lib/libz.so.1.2.3        /usr/lib/libz.so.1
/lib64/libz.so.1.2.3  /usr/lib64/libz.so.1      /usr/lib/libz.so.1.2.3
/lib/libz.so.1        /usr/lib64/libz.so.1.2.3

[root@nim1 ~]# grep libz /usr/lib64/guestfs/initramfs.epel-5.x86_64.supermin.hostfiles

[root@nim1 ~]# rpm -qa --qf '%{name} %{version} %{arch}\n' | grep zlib
zlib 1.2.3 i386
zlib 1.2.3 x86_64

[root@nim1 ~]# rpm -qf /lib64/libz.so.1

[root@nim1 ~]# rpm -qf /lib/libz.so.1

[root@nim1 ~]# rpm -ql zlib-1.2.3-4.el5.i386

[root@nim1 ~]# rpm -ql zlib-1.2.3-4.el5.x86_64

[root@nim1 ~]# uname -a

Comment 7 Richard W.M. Jones 2011-10-24 14:55:15 UTC
Just updating my machine to RHEL 5.7 to see if I can
reproduce the problem there.

Comment 8 Richard W.M. Jones 2011-10-24 16:58:06 UTC
I can reproduce this in RHEL 5.7.  It seems like they've
moved the zlib libraries around (but with symlinks).

This needs a libguestfs rebuild which I have kicked off here:
