## Same structure, for removed inventories (after deletion)
dn: ou=Removed Inventories,ou=Inventories,cn=rudder-configuration
objectclass: top
objectclass: organizationalUnit
ou: Removed Inventories
description: Store inventories removed from Rudder

# Machines, pending @ example.org
dn: ou=Machines,ou=Removed Inventories,ou=Inventories,cn=rudder-configuration
objectClass: top
objectClass: organizationalUnit
ou: Machines
description: Containers for servers from ou=Nodes, such as physical machines or virtual machines.

# Nodes, pending @ example.org
dn: ou=Nodes,ou=Removed Inventories,ou=Inventories,cn=rudder-configuration
objectClass: top
objectClass: organizationalUnit
ou: Servers
description: Logical servers, an OS installation. May be on a virtual machine or a physical machine, from ou=Machines.

I do not think that this test is optimal:

LDAP_TEST_REMOVED_INVENTORIES=$(/opt/rudder/sbin/slapcat 2>/dev/null | grep "Removed Inventories" | wc -l)
if [ ${LDAP_TEST_REMOVED_INVENTORIES} -ne 4  ]; then

In fact, it is dangerous, for several reasons:

The number of lines matched will be variable depending on the number of nodes removed... each one will add one to this number, causing your test to fail, and attempt to re-add these entries, thus making the rudder-upgrade script fail.
Matching a short piece of full text like "Removed Inventories" on the whole contents of the LDAP directory is very imprecise. What if someone creates a Directive with "Removed Inventories" in the description? It will be matched and cause this test to be wrong.

A better test can be acheived by matching the exact line you're looking for, and one that is unique, maybe something like this:

LDAP_TEST_REMOVED_INVENTORIES=$(/opt/rudder/sbin/slapcat 2>/dev/null | grep '^dn: ou=Removed Inventories,ou=Inventories,cn=rudder-configuration$' | wc -l)
if [ ${LDAP_TEST_REMOVED_INVENTORIES} -ne 1  ]; then

Ok, you're right. I thought that "Removed Inventories" will be unique to 4 entries but I was wrong. I will do a more precise test like you suggested.
