== HTTPD ==
* mod_ssl is not installed (should be listed as a requirement for e-smith-apache)
yum install mod_ssl
* mod_auth_tkt used to provide the perl Apache::AuthTkt module. It's not the case anymore so this module is now missing, preventing the server-manager to load. A standalone perl-Apache-AuthTkt rpm is available on repoforge
* perl-suidperl is not installed (should be added as required by e-smith-manager)
yum install perl-suidperl
* after fixing those two issues, we get a blank page after login on the server-manager, logs (admin_error_log) print the following error:
[Fri Jan 25 22:59:23 2013] [error] [client 127.0.0.1] Can't locate object method "host" via package "URI::_generic" at /etc/e-smith/web/common/cgi-bin/login line 162., referer: https://192.168.7.154/server-common/cgi-bin/login?redirect=1&back=http%253a%252f%252f192.168.7.154%252fserver-manager%252f
* If we try to access the server-manager again, it's working (as we already have our cookie). It's just the redirection after the login which is broken
==Squid ==
squid doesn't start, and the folowwing errors are printed in /var/log/messages

</pre>
So several problems here:
* We need to remove the -D arg from /var/services/squid/run
* We need to remove the file /etc/e-smith/templates/etc/squid/squid.conf/20ACL00all (which just contains acl all src 0.0.0.0/0.0.0.0 and is not needed anymore)
* we need to convert acl in CIDR notation (for now, they are retrieved using esmith::NetworksDB::local_access_spec, which doesn't support cidr)
* we need to remove /etc/e-smith/templates/etc/squid/squid.conf/35extension_methods (extensionmethods is not supported anymore as it was not usefull anymore)
== clamav ==
* user created during clamd installation is now clam (used to be clamav), templates for /etc/clamd.conf need to be adjusted
* DatabaseDirectory is now /var/lib/clamav (used to be /var/clamav), templates for /etc/clamd.conf need to be adjusted
* LocalSocket should now be /var/run/clamav/clamd.socket (use to be /var/clamav/clamd.socket), templates for /etc/clamd.conf need to be adjusted
* Permissions on /var/spool/qpsmtpd/ (provided by smeserver-qpsmtpd) should also be adjusted (clam instead of clamav group)
== qpsmtpd ==
Doesn't start. See http://bugs.contribs.org/bugs/show_bug.cgi?id=7223
@400000005102ec023094f554 Can't locate Qpsmtpd/TcpServer.pm in @INC (@INC contains: lib /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at /usr/bin/qpsmtpd-forkserver line 13.
@400000005102ec023094fd24 BEGIN failed--compilation aborted at /usr/bin/qpsmtpd-forkserver line 13
* We should rebuild qpsmtpd with a simple spec file change to use /usr/share/perl5/vendor_perl instead of /usr/lib/perl5/site_perl
== radius ==
Radiusd doesn't start with this error
radiusd: Error: No log destination specified
* To fix this error, we need to add ”-l stdout” as argument to radiusd in /var/service/radiusd/run
After that, the following error occures:

* To fix this, we have to install freeradius-ldap, which is now in its own package (freeradius-ldap should be added as required by e-smith-radiusd)
== syslog ==
* rsyslog is now used instead of syslog. We need to replace all occurance of syslog with rsyslog (see http://bugs.contribs.org/bugs/show_bug.cgi?id=7221)
== upstart/sysvinit ==
* in EL6, SysVinit is replaced with upstart, and upstart doesn't support rc7 runlevel. One option is to move to rc4 as default runlevel. See http://bugs.contribs.org/bugs/show_bug.cgi?id=7217 and http://bugs.contribs.org/bugs/show_bug.cgi?id=7227
== LDAP ==
* openldap-servers is not installed (missing a Requires: openldap-servers in e-smith-ldap's spec file)
* we need to add -f /etc/openldap/slapd.conf arg when launching slapd (in /var/service/ldap/run), or it will try to convert this file the the new slapd.d style
* schema file /etc/openldap/schema/redhat/autofs.schema is missing. In EL5, it was provided by openldap-servers
* slapd fails to start with this error:
/etc/openldap/slapd.conf: line 27: unknown directive <schemacheck> outside backend info and database definitions
== console ==
* kudzu has been removed from EL6, so now this bug http://bugs.contribs.org/show_bug.cgi?id=3596 needs to be fixed so we can detect network interfaces.
* Here's a code snipet which seems to work, the only thing missing is to retrieve the interface description from hwdata, for now, it just return the name 'eth0, eth1 etc…) instead of the description (in esmith/ethernet.pm)
