It sounds like something required wasn't ready, and caused boot to get
dropped at emergency.target. By the time you control-D to continue,
the require thing is ready so boot continued. Speculation.

Anyway, if you can locate /run/initramfs/rdsosreport.txt and post it
somewhere, that'd be useful at figuring out what the problem is. Also
include version of dracut:
$ rpm -q dracut
