@@ -400,8 +400,6 @@ virt-sysprep ideas Kazuo Moriwaka adds: - "yum clean all" (or the equivalent) to remove yum caches - - lvm PV and VG have its UUID. 'pvchange -u' and 'vgchange -u' generate - new UUID (causes trouble with clustered LVM). - swap devices (both of block device and file) should be wiped. This may good for security purpose, and size. I found virt-sparsify can clear swap partition. diff --git a/po/POTFILES-ml b/po/POTFILES-ml index b2c15a10..11aab055 100644 --- a/po/POTFILES-ml +++ b/po/POTFILES-ml @@ -22,6 +22,7 @@ sysprep/sysprep_operation_flag_reconfiguration.ml sysprep/sysprep_operation_hostname.ml sysprep/sysprep_operation_kerberos_data.ml sysprep/sysprep_operation_logfiles.ml +sysprep/sysprep_operation_lvm_uuids.ml sysprep/sysprep_operation_machine_id.ml sysprep/sysprep_operation_mail_spool.ml sysprep/sysprep_operation_net_hwaddr.ml diff --git a/sysprep/Makefile.am b/sysprep/Makefile.am index 5f5e11e5..e56a9718 100644 --- a/sysprep/Makefile.am +++ b/sysprep/Makefile.am @@ -41,8 +41,8 @@ CLEANFILES = \ operations = \ abrt_data bash_history blkid_tab ca_certificates cron_spool \ dhcp_client_state dhcp_server_state dovecot_data flag_reconfiguration \ - hostname kerberos_data logfiles machine_id mail_spool net_hwaddr \ - package_manager_cache pam_data puppet_data_log random_seed \ + hostname kerberos_data lvm_uuids logfiles machine_id mail_spool \ + net_hwaddr package_manager_cache pam_data puppet_data_log random_seed \ rhn_systemid samba_db_log script smolt_uuid ssh_hostkeys \ ssh_userdir sssd_db_log udev_persistent_net user_account \ utmp yum_uuid diff --git a/sysprep/sysprep_operation_lvm_uuids.ml b/sysprep/sysprep_operation_lvm_uuids.ml new file mode 100644 index 00000000..f23f5128 --- /dev/null +++ b/sysprep/sysprep_operation_lvm_uuids.ml @@ -0,0 +1,53 @@ +(* virt-sysprep + * Copyright (C) 2012 Red Hat Inc. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
