Description of problem: Booting from a LUKS partition mounted over iSCSI takes 90 seconds. This is because LUKS systemd service blocks the iSCSI systemd service. Once the LUKS service times out after 90 seconds, the iSCSI drive is mounted and decrypted and the boot continues. If you switch 95iscsi/iscsiroot.sh to use iscsistart instead of systemd-run, the problem goes away Version-Release number of selected component (if applicable): dracut 033-360.el7_2 dracut-network 033-360.el7_2 How reproducible: 100% Steps to Reproduce: 1. Create a system with an iSCSI root LUKS partition. crypttab and key are both stored in dracut image. Kernel params are used to specify iSCSI info crypttab device /dev/sda1 root=/dev/dm-0 netroot=<iscsi.target> 2.

Does it help to add: -p 'DefaultDependencies=no' \ to the systemd-run call?
