<flag name="sha512">
Switch Linux-PAM's pam_unix module to use sha512 for passwords
hashes rather than MD5. This option requires
- <pkg>>=sys-libs/pam-1.0.1</pkg> built against
- <pkg>>=sys-libs/glibc-2.7</pkg>, if it's built against an
+ <pkg>sys-libs/pam</pkg> version 1.0.1 built against
+ <pkg>sys-libs/glibc</pkg> 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
