tmpfiles, man: Add xattr support to tmpfiles
This patch makes it possible to set extended attributes on files created by tmpfiles. This can be especially used to set SMACK security labels on volatile files and directories. It is done by adding new line of type "t". Such line should contain attributes in Argument field, using following format: name=value All other fields are ignored. If value contains spaces, then it must be surrounded by quotation marks. User can also put quotation mark in value by escaping it with backslash. Example: D /var/run/cups - - - - t /var/run/cups - - - - security.SMACK64=printing
