Just tested a full upgrade from alpha6 to beta6~git(from today) and it works fine.

Dunno how this will affect SLES or RHEL though? RPMs don't seem to have this notion of taking over a file...

I don't know but I guess it will not affect RPM since I didn't find any documentation about this case.

• If we only install rudder-inventory-ldap, during upgrade (from alpha7 to nightly) zypper will complain about missing backup files:
  

  [...]
  (with --nodeps --force) Error: Subprocess failed. Error: RPM failed: /var/rudder/ldap/backup/openldap-data-pre-upgrade-20120918145601.ldif: No such file or directory

  [...]
  

• If the installation of rudder-server-root is complete, the migration doesn't make any error:
  

  [...]

  You can safely remove the backups in /var/rudder/ldap/openldap-data-backup-upgrade-to-/
  and /var/rudder/ldap/backup/openldap-data-pre-upgrade-20120918150411.ldif.ldapEntriesFixed

RPM definitively doens't manage this case.

This is an error made because of the folder /var/rudder/ldap/backup/ missing. If the folder is present, no error is displayed. We could prevent this by adding "mkdir -p /var/rudder/ldap/backup/" in the preinst script of rudder-inventory-ldap.

Some error is show in the display, because "/var/rudder/ldap/openldap-data-backup-upgrade-to-/" doesn't exist. This is because of the use of $2 in the SPEC file although this should be used for Debian. Besides, there is a typo in the echo:

echo "You can safely remove the backups in /var/rudder/ldap/openldap-data-backup-upgrade-to-$2/" 

echo "You can safely remove the backups in /var/rudder/ldap/openldap-data-backup-upgrade-to-$2-${TIMESTAMP}/" 

like the code above in the SPEC file.

RPM definitively doens't manage this case.

Well, it seems that this is not true. If I use the command rpm, there will be an error:

# rpm -Uvh rudder-inventory-ldap-2.4.0.beta6.git-1.x86_64.rpm 
Preparing...                ########################################### [100%]
    file /opt/rudder/share/upgrade-tools/rudder-upgrade-LDAP-schema-2.3-2.4-PI-PT-CR-names-changed.pl from install of rudder-inventory-ldap-2.4.0.beta6.git-1.x86_64 conflicts with file from package rudder-webapp-2.4.0.alpha7-1.SLES.11.noarch

But it doesn't prevent from upgrading the packages with zypper on SLES.

• Ensure in the preinst that /var/rudder/ldap/backup/ exist before trying to create backup files in it.
• Remove $2 from SPEC files

But it doesn't seem to lead into errors in SLES.

And to add informations about conflict files with RPM, it seems that the dependencies are resolved if all the packages are used with RPM:

With only rudder-inventory-ldap package:

sles1164test:~ # rpm -Uvh rudder-inventory-ldap-2.4.0.beta4-1.SLES.11.x86_64.rpm 
Preparing...                ########################################### [100%]

With the two of packages in conflict

sles1164test:~ # rpm -Uvh rudder-inventory-ldap-2.4.0.beta4-1.SLES.11.x86_64.rpm rudder-webapp-2.4.0.beta4-1.SLES.11.noarch.rpm
