Rudder

On a server running rudder 2.10 on debian stable.

Example of error appearing when restarting postfix:

sendmail: /opt/rudder/lib/libdb-5.1.so: no version information available (required by /usr/lib/libpostfix-util.so.1)

/etc/ld.so.conf.d contains:

libc.conf  rudder-inventory-ldap.conf    x86_64-linux-gnu.conf

Rudder libraries are retrieved before standard x86_64-linux-gnu.conf libraries:

2 possible fixes to make postfix happy, but break rudder-slapd:

mv rudder-inventory-ldap.conf zz_rudder-inventory-ldap.conf
ldconfig

or

cp x86_64-linux-gnu.conf 01x86_64-linux-gnu.conf
ldconfig

Then postfix is happy:

ldd /usr/lib/libpostfix-util.so.1
    linux-vdso.so.1 =>  (0x00007fff829fc000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fa1005c2000)

    libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fa0feddd000)

but then rudder-slapd is broken

So for now, postfix is complaining, but still working.
