Customize mock the mount /dev and /selinux from the base system. 2. Create a chroot. 3. Start the assembly of the image, using a mock. Actual results: The build process hangs at the stage of handling to the /sbin/dmsetup. Expected results: Creating an image or priryvanie process of returning an error flag. Additional info: If the parameters causing the / sbin / dmsetup (see) add keys "," we see that the dmsetup expects what that events from udev. <mock-chroot>[root@kojicos /]# /usr/bin/livecd-creator -c /tmp/koji-image-ext-centos6-livecd-build-170.ks -d -v --logfile /tmp/livecd.log --cache /tmp/koji-liviveCD-CentOS6-0.0.1-1 mke2fs 1.41.12 (17-May-2010) Discarding device blocks: done Filesystem label=_test-LiveCD-Cen OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 65536 inodes, 262144 blocks 2621 blocks (1.00%) reserved for the super user First data block=0 Maximum filesystem blocks=268435456 8 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376 Writing inode tables: done Creating journal (8192 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 29 mounts or 180 days, whichever comes first.

In repository https://github.com/solooboroten/fedora-livecd offer options to add options --noudevsync: 1. Branch el6/noudevsync (see https://github.com/solooboroten/fedora-livecd/tree/el6/noudevsync), for EPEL6: https://github.com/solooboroten/fedora-livecd/commit/6e98bec0cc16195d776096886db102461e174312 . This version of checked package livecd-tools-13.4.4. This variant works. Tested self-assembled package livecd-tools-13.4.4-2.el6.altell1.1 (see https://github.com/solooboroten/fedora-livecd/commit/b049ccc9daafdad57092788dc10747f5ab794cb7). 2. Branch noudevsync (see https://github.com/solooboroten/fedora-livecd/tree/noudevsync), for master: https://github.com/solooboroten/fedora-livecd/commit/a65871f531c48d32084dd4ad039ac0724ef47014 .
You shouldn't be running mock as the root user. Add a user to the mock group and run it from that account, doing it as root can result in odd behavior.
