with encrypted home, /etc/legal is printed twice on every login

[Роман Донченко]

I have an encrypted home directory, and whenever I log in at the console, the contents of /etc/legal are printed twice (after the system load stats).

This happens because:

1) pam_motd.so uses ~/.cache/motd.legal-displayed to record the fact that /etc/legal has already been displayed;

2) the home directory is read-only until ecryptfs is mounted;

3) the MOTD is printed before ecryptfs is mounted, because in /etc/pam.d/login the pam_motd.so rules come before "@include common-session" (which includes the pam_ecryptfs.so rule).

The fix should be simple - just change the order so that the pam_motd.so rules come after "@include common-session". (The Apport report says my /etc/pam.d/login is modified, because I did just that.)

I shouldn't have reassigned this bug to pam. Sorry!
