dracut is blocked when --force-drivers is set empty

[jiayi0118]

Issue Description

Call the following command, dracut will be blocked.

# dracut --force-drivers " " ./test.img

Version

master

Analysis

The code locates in:

dracut/dracut-init.sh

Line 1083 in 4971f44

read -r -d '' -a args

The implementation will read from input when instmods has no kernel modules assigned.

On the other hand, the following usage of dracut seems legal and the blocking issue will be resolved.

# dracut --force-drivers " " ./test.img <<< xxx

What I want to ask is that whether this issue is a bug or just a rare usage?
