dracut [PATCH] Parameter expansion occurs before command evaluation.

[John Reiser <jreiser@xxxxxxxxxxxx>]

Bash shell expands all ${parameter} before evaluating a command.
For multiple declarations and assignments within the same 'local' command,
then new variables or new values that appear towards the left
do not affect parameter expansion towards the right.

Subject: [PATCH] Parameter expansion occurs before command evaluation.

${parameter} on the right is expanded before evaluating "local var=value"
on the left.
