[gentoo-user] Cannot have the default USE='static pam' for sys-apps/busybox

[Gevisz]

While doing recent wold updates I get the following message:

* Messages for package sys-apps/busybox-1.23.0-r1:
* You cannot have USE='static pam'.  Assuming static is more important.

However, I never set any of those two flags neither in /etc/portage/make.conf
no in /etc/portage/packag.use. So, it is set by default.

So, why the massage above?

Now, after finally setting
 sys-apps/busybox -pam
in /etc/portage/packag.use and rebuilding the package, I have

$ equery uses busybox
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for sys-apps/busybox-1.23.0-r1:
 U I
 - - debug         : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see
                     http://www.gentoo.org/proj/en/qa/backtraces.xml
 + + ipv6          : Add support for IP version 6
 - - livecd        : !!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used during livecd building
 - - make-symlinks : Create all the appropriate symlinks in /bin and /sbin.
 - - math          : Enable math support in gawk (requires libm)
 - - mdev          : Create the appropriate symlink in /sbin and install mdev.conf and support files
 - + pam           : Add support for PAM (Pluggable Authentication Modules) - DANGEROUS to arbitrarily flip
 - - savedconfig   : Use this to restore your config from /etc/portage/savedconfig ${CATEGORY}/${PN}. Make sure your USE flags allow for appropriate dependencies
 - - sep-usr       : Support a separate /usr without needing an initramfs by booting with init=/ginit
 + + static        : Make the system rescue shell (/bin/bb) static so you can recover even when glibc is broken
 - - syslog        : Enable support for syslog
 - - systemd       : Support systemd

which confirms that +pam and +static has been set in busybox by default.
