svn commit: r327575 - head/lib/libefivar

[Warner Losh]

Author: imp

New Revision: 327575
URL: https://svnweb.freebsd.org/changeset/base/327575

Log:
  Need to convert '/' back to '\' when creating a path. Ideally, this
  would be filesystem type dependent, but that's difficult to accomplish
  and it's unclear how the UEFI firmware will cope. Be conservative and
  make boot loaders cope instead.
