Package: libcap2
Version: 2.09-1
Severity: wishlist
Linux 2.6.25.6 has the following in kernel/capability.c:
--8<---------------cut here---------------start------------->8---
/*
* Version 2 capabilities worked fine, but the linux/capability.h file
* that accompanied their introduction encouraged their use without
* the necessary user-space source code changes. As such, we have
* created a version 3 with equivalent functionality to version 2, but
* with a header change to protect legacy source code from using
* version 2 when it wanted to use version 1. If your system has code
* that trips the following warning, it is using version 2 specific
* capabilities and may be doing so insecurely.
*
* The remedy is to either upgrade your version of libcap (to 2.10+,
* if the application is linked against it), or recompile your
* application with modern kernel headers and this warning will go
* away.

The result is that with zsh, my login shell, being linked against
libcap2, I get this warning on the first login. Would be nice if you
could package libcap2 2.10 which, according to the comment above, should
remedy this.
