| - | Replace symbolic link from ''/etc/motd'' to ''/var/run/motd'' with a file that has the information we want. | + | On Debian, you can't edit ''/etc/motd'' directly and expect it to stay |
| + | because ''/etc/motd'' is just a symbolic link to ''/var/run/motd'' and the | ||
| + | symbolic link is likely to be recreated by future patches from Debian. | ||
| + | ''/etc/init.d/bootmisc.sh'' rebuilds ''/var/run/motd'' on every reboot, using | ||
| + | /etc/motd.tail. So to make a permanent change on Debian systems, | ||
| + | edit ''/etc/motd.tail'', instead of ''/etc/motd'', to put in the information we want. | ||
