So I asked for some help on configuring mail. There were many kind
soles on the leaf-user list that helped out. From this, I have created
some mail functionality that may be useful to others. So I'd like to
package it in a way that my changed files can be absorbed into the other
packages where they belong. I think the most important accomplishment
that I made was that the mail functionality can be turned on and off in
the lrp.conf file. This file is on a menu that an average user can get
to easily. I looked at many other examples and the user had to get down
in the script and make changes. However, I borrowed heavily from others
examples. Ya know...."The first law of reverse engineering is to steal
the best."
I believe I fixed the cron path issue. I created a script to send
dynamic ip addresses to a list of email addresses. I created a way to
send log files to a list of email addresses. This is different than the
other email status emails. I had to modify dhclient-exit-hooks,
multicron-d, lrp.conf, and created a new ipmail script. The scripts
should be absorbed in dhclient.lrp, etc.lrp, etc.lrp, and root.lrp
respectfully. At this point I am having trouble locating the correct
documentation, or I am not putting the information together correctly in
my head.
I have no preference to the names and they can be changed to more ideal
candidates. Eventually I would hope that these ideas would wind up in a
LEAF distro or two. I would hope that the package would exist until
taken over in this manor. Here's what my design goal is
lrpkg -i mailtool.lrp
configure lrp.conf
backup root.lrp
backup etc.lrp
backup dnclient.lrp
The first problem I am having is on my DCD102 system. I put ipmail in
/usr/bin/ipmail. I then performed a backup of root.lrp. ipmail was not
in the backup. I read the "LRP packaging details and limitations" FAQ
http://sourceforge.net/docman/display_doc.php?docid=1461&group_id=13751.
I tried to edit root's .list file and could not make my new file stick
in the backup.
So here are my list of newbie packaging questions?
Is ipmail correctly located in /usr/bin?
Should I first create a package and then install it?
Are the file names ok?
Are the variable names listed below ok?
Are there any other shell script techniques that I should be
following?
Can files be absorbed in another package?
Below are the diffs.
