mailman should be built using INSTALLDIR="/usr" and --with-var-prefix="/var/mailman", so seperate static content with mutable content. This would also be closer to LFS. -A
Here is what the message after emerging mailman says: * The home directory for mailman has been moved from /var/mailman * (pre 2.1.1-r2) or /home/mailman (2.1.1-r3) to /usr/local/mailman * This should hopefully solve any problems, and this is what the mailman * default is. (Any existing config has been saved in the * new home directory.) This leads me to believe that the use of /usr/local is recent and deliberate.
closing with 2.1.4
