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:elogind - Use pam_elogind module to register user sessions with elogind. 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:nullok - Enable the nullok option with the pam_unix module. This allows people to login with blank passwords. sys-auth/pambase:pam_krb5 - 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:pam_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/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:securetty - Enable pam_securetty module in the login stack. Not generally relevant anymore as the login stack only refers to local logins and local terminals imply secure access in the first place. 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 version 1.0.1 built against sys-libs/glibc version 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:systemd - Use pam_systemd module to register user sessions in the systemd control group hierarchy. sys-auth/passwdqc:utils - Install pwqcheck and pwqgen helper utilities sys-auth/polkit:consolekit - Use sys-auth/consolekit for session tracking sys-auth/polkit:elogind - Use sys-auth/elogind for session tracking sys-auth/polkit:systemd - Use sys-apps/systemd for session tracking sys-auth/ssh-ldap-pubkey:schema - Install a copy of the LPK schema, only needed on LDAP servers. sys-auth/sssd:acl - Build and use the cifsidmap plugin 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:curl - Enable HTTP engine for S3 and WebDav support support via net-misc/curl 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/fio:tcmalloc - Link against dev-util/google-perftools by default which will speed up USE=rbd up to 20% 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:udf - Include UDF support (sys-fs/udftools) sys-block/gparted:wayland - Enable interim workaround to allow running GParted under Wayland by granting permission to the X11 display using x11-apps/xhost. sys-block/gparted:xfs - Include XFS support (sys-fs/xfsprogs, sys-fs/xfsdump) sys-block/nbd:netlink - Add support for netlink protocol via dev-libs/libnl 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.
