Re: [Kimchi-devel] [PATCH 2/3] issue #565: Allow a template's ISO to be a block device

The current template code checks whether an ISO path is a regular file (i.e. not a directory, not a char device, not a link). However, a block device may also be a valid ISO path because storage volumes belonging to logical pools are always block devices (e.g. /dev/mypool/myvol.iso), and they should also be used to create templates. Instead of allowing only regular files to be used as template ISOs, allow block devices as well. Fix issue #565 (Allow creating templates with device files).
