 On Debian-based systems, from interfaces(5) manpage:

 "Additionally, all options given in an interface definition  stanza  are
 exported to the environment in upper case with "IF_" prepended and with
 hyphens converted to underscores and non-alphanumeric  characters
 discarded."

 Which would imply that it is expected that a stanza may contain
 alphanumeric, hyphens and underscores. interfaces.aug should match that.

 One such case where it fails is with the vde2-switch stanza (from
 /etc/network/if-pre-up.d/vde2)
