Running dracut in a chroot environment, which has /dev not correctly
966cef
setup will result in errors like:
966cef
966cef
/usr/bin/lsinitrd: line 164: /dev/fd/62: No such file or directory

cpio: Malformed number �OK��

966cef
This is because bash wants /dev/fd/<num> for constructs like:
966cef
foo < <$(bar)
