Subject: [PATCH] iscsiroot: remove bashisms
According to the dracut README, module code to be run in
the initrd must be POSIX-compliant. Replace remaining
bashisms (as reported by checkbashisms) with POSIX compliant
code.
The use of "type" is not strictly POSIX compliant, but it's
all over the place in dracut code. dash supports it, anyway.
