Not recommended. sys-auth/elogind:apparmor - Enable AppArmor support sys-auth/fingerprint-gui:upekbsapi - Add UPEK BSAPI drivers for identify functions on some readers sys-auth/keystone:memcached - Installs dependencies needed for using memcached as a backend sys-auth/keystone:mongo - Installs dependencies needed for using mongo as a backend sys-auth/munge:gcrypt - Use libgcrypt instead of openssl sys-auth/nss-mdns:search-domains - Honour search domains from /etc/resolv.conf (see bug #201948 for possible side effects) sys-auth/nss-pam-ldapd:utils - Install the command-line utilities sys-auth/oath-toolkit:pam - Build PAM module for pluggable login authentication for OATH sys-auth/oath-toolkit:pskc - Build tools & library for the Portable Symmetric Key Container (PSKC) format per RFC6030 sys-auth/pam_mktemp:prevent-removal - If supported, set EXT2_APPEND_FL on /tmp/.private to prevent temporary directories from being removed sys-auth/pam_mysql:openssl - Use OpenSSL for md5 and sha1 support sys-auth/pam_pkcs11:nss - Use Mozilla NSS (dev-libs/nss) as provider for PKCS#11 access, rather than using OpenSSL with a custom implementation of the PKC#11 protocol. sys-auth/pam_pkcs11:pcsc-lite - Build the card_eventmanager binary used to detect card removal and lock the sessions. This needs sys-apps/pcsc-lite. sys-auth/pam_u2f:debug - Enable debug messages using the pam logging macros. (Note: these will be visible on stdout for terminal logins). sys-auth/pambase:consolekit - Enable pam_ck_connector module on local system logins. This allows for console logins to make use of ConsoleKit authorization. sys-auth/pambase:cracklib - Enable pam_cracklib module on system authentication stack. This produces warnings when changing password to something easily crackable. It requires the same USE flag to be enabled on sys-libs/pam or system login might be impossible. sys-auth/pambase:debug - Enable debug information logging on syslog(3) for all the modules supporting this in the system authentication and system login stacks. sys-auth/pambase:gnome-keyring - Enable pam_gnome_keyring module on system login stack. This enables proper Gnome Keyring access to logins, whether they are done with the login shell, a Desktop Manager or a remote login systems such as SSH. sys-auth/pambase:kerberos - Enable pam_krb5 module on system auth stack, as an alternative to pam_unix. If Kerberos authentication succeed, only pam_unix will be ignore, and all the other modules will proceed as usual, including Gnome Keyring and other session modules. It requires sys-libs/pam as PAM implementation. sys-auth/pambase:minimal - Disables the standard PAM modules that provide extra information to users on login; this includes pam_tally (and pam_tally2 for Linux PAM 1.1 and later), pam_lastlog, pam_motd and other similar modules. This might not be a good idea on a multi-user system but could reduce slightly the overhead on single-user non-networked systems. sys-auth/pambase:mktemp - Enable pam_mktemp module on system auth stack for session handling. This module creates a private temporary directory for the user, and sets TMP and TMPDIR accordingly. sys-auth/pambase:passwdqc - Enable pam_passwdqc module on system auth stack for password quality validation. This is an alternative to pam_cracklib producing warnings, rejecting or providing example passwords when changing your system password. It is used by default by OpenWall GNU/*/Linux and by FreeBSD. sys-auth/pambase:sha512 - Switch Linux-PAM's pam_unix module to use sha512 for passwords hashes rather than MD5. This option requires >=sys-libs/pam-1.0.1 built against >=sys-libs/glibc-2.7, if it's built against an earlier version, it will silently be ignored, and MD5 hashes will be used. All the passwords changed after this USE flag is enabled will be saved to the shadow file hashed using SHA512 function. The password previously saved will be left untouched. Please note that while SHA512-hashed passwords will still be recognised if the USE flag is removed, the shadow file will not be compatible with systems using an earlier glibc version. sys-auth/pambase:ssh - Enable pam_ssh module on system auth stack for authentication and session handling. This module will accept as password the passphrase of a private SSH key (one of ~/.ssh/id_rsa, ~/.ssh/id_dsa or ~/.ssh/identity), and will spawn an ssh-agent instance to cache the open key. sys-auth/passwdqc:utils - Install pwqcheck and pwqgen helper utilities sys-auth/polkit:elogind - Use sys-auth/elogind instead of sys-auth/consolekit for session tracking sys-auth/polkit:systemd - Use sys-apps/systemd instead of sys-auth/consolekit for session tracking sys-auth/sssd:acl - Build and use the cifsidmap plugin sys-auth/sssd:augeas - Build internal configuration library sys-auth/sssd:autofs - Build helper to let net-fs/autofs use sssd provided information sys-auth/sssd:locator - Install sssd's Kerberos plugin sys-auth/sssd:manpages - Build man pages with dev-libs/libxslt sys-auth/sssd:netlink - Add support for netlink protocol via dev-libs/libnl sys-auth/sssd:nfsv4 - Add support for the nfsv4 idmapd plugin provided by net-libs/libnfsidmap sys-auth/sssd:ssh - Build helper to let net-misc/openssh use sssd provided information sys-auth/sssd:sudo - Build helper to let app-admin/sudo use sssd provided information sys-auth/ykpers:consolekit - Use sys-auth/consolekit and virtual/udev to allow access to the YubiKey HID device to the console user. sys-block/f3:extra - Build the additional f3probe, f3brew and f3fix utility (requires sys-block/parted and virtual/udev) sys-block/fio:aio - Enable AIO ioengine sys-block/fio:glusterfs - Enable GlusterFS gfapi support via sys-cluster/glusterfs sys-block/fio:gnuplot - Install tools for generating gnuplots sys-block/fio:numa - Enable numa support sys-block/fio:rbd - Enable Rados block device support via sys-cluster/ceph sys-block/fio:rdma - Enable infiniband support via sys-fabric/librdmacm sys-block/gparted:btrfs - Include Btrfs support (sys-fs/btrfs-progs) sys-block/gparted:cryptsetup - Include LUKS volume support (sys-fs/cryptsetup) sys-block/gparted:dmraid - Support for dmraid devices, also known as ATA-RAID, or Fake RAID. sys-block/gparted:f2fs - Include F2FS support (sys-fs/f2fs-tools) sys-block/gparted:fat - Include FAT16/FAT32 support (sys-fs/dosfstools) sys-block/gparted:hfs - Include HFS support (sys-fs/hfsutils) sys-block/gparted:jfs - Include JFS support (sys-fs/jfsutils) sys-block/gparted:mdadm - Support for Linux software RAID. sys-block/gparted:ntfs - Include NTFS support (sys-fs/ntfs3g) sys-block/gparted:reiser4 - Include ReiserFS4 support (sys-fs/reiser4progs) sys-block/gparted:reiserfs - Include ReiserFS support (sys-fs/reiserfsprogs) sys-block/gparted:xfs - Include XFS support (sys-fs/xfsprogs, sys-fs/xfsdump) sys-block/open-iscsi:rdma - Support iSCSI over RDMA sys-block/open-iscsi:tcp - Support iSCSI over TCP sys-block/parted:debug - Enable debugging as encouraged by upstream: [The default configuration] includes --enable-debug (by default), which contains many assertions. Obviously, these "waste" space, but in the past, they have caught potentially dangerous bugs before they would have done damage, so we think it's worth it. Also, it means we get more bug reports ;) sys-block/parted:device-mapper - Enable device-mapper support from sys-fs/lvm2 in parted sys-block/partimage:nologin - Do not include login support when connecting partimaged sys-block/sas2ircu:efi -
