rust-motd Setup

#rust  #motd  #systemd-timer 

2022-03-04 update:

gdm 用户最好不要启用 motd. 否则在登录界面会卡很久才进去.

有办法可以禁用这一行为, see https://bbs.archlinux.org/viewtopic.php?pid=1684018#p1684018

moving the following line:

session    optional   pam_motd.so          motd=/etc/motd

from /etc/pam.d/system-login to /etc/pam.d/sshd.

The result is that the motd is no longer displayed in gdm, but it’s still displayed when logging in through ssh.

Beautiful, useful, configurable MOTD generation with zero runtime dependencies
