I do similiar things for some local files that require very special
commands to take effect. But:
- I put the commands on top of the file. (Matter of taste.)
- I use vi as root, hence I execute them via cut-and-paste.
- Above message might help new Debian users.
- Stores the "make the system use in data" command near the relevant data.
- It promotes using Emacs as root.
- Some people may dislike such texts.
- This entry has to be recognized by scripts that automatically
append new antries.
IMHO the real solution is to make all the daemons check themselves
whether their config files have changed. This obsoletes the whole
problem, but it is contrary to Unix tradition.
Implementation: If you seldomly receive requests the daemon could stat
the config files on every request. Otherwise you have to do the same
thing time driven. A better approach were a select(2) extension that
informs you whenever a file was modified.
