Subject: [PATCH] lvm: fix thin recognition

The global var setting was happening in a pipe and did not have an

effect.

Use <<<$() instead.

< <() cannot be used, because dracut is called in chroot's environments,

where /dev/fd does not point to /proc/self/fd, but bash wants

/dev/fd/<num> for this construct.
