Description Todd C. Miller 2004-05-11 05:00:32 UTC 
      login.conf(5) states that "Capabilities that set environment variables are scanned for both `~' and `$' characters, which are substituted for a user's home directory and name respectively.  To pass these characters literally into the environment variable, escape the character by preceding it with a backslash '\'.

Fix: 

Either remove the support for escaping the characters or document its deficiencies.
How-To-Repeat:       Try escaping a ~ or $ in a setenv or path capability in login.conf or ~/.login_conf.

Comment 2 Todd C. Miller 2004-08-09 22:55:18 UTC 
One way to make the behavior match the documentation is to use
cgetustr(3) when interpreting a "path" or "setenv" capability.  That
way the normal backslash escape stuff is not done.  This is what I
just did in OpenBSD (I also implemented the normal cgetstr(3)
escaping for consistency).
