[Bug 591823] Re: "File descriptor \d+ (\S+) leaked on lvs invocation."

[Mikko Rantalainen]

I would guess some files are left open when
grub_util_pull_lvm_by_command() calls grub_util_exec_pipe() in grub2
/grub-core/osdep/unix/getroot.c

  This is a slightly controversial bug and it's not yet fixed either way
  (aka fix not to leak file descriptors or stop warning by default)
