Yesno depending on how the meta package is installed, automatically or
manual. However, writhing scripts to manage something to a user's
individual needs isn't hard to do.

I don't need to care about dkms, an universal script must care about it,
too. I only need to care about lowlatency, an universal script should
be able to handle all types of kernels, including local builds. An
universal script should provide options, for example to keep two or
tree kernels of the same type.

My script does something unimportant for other users, it removes and
adds links required by the used bootloader. The script doesn't do
anything automatically in the first place, but it suggests something I
could copy and paste and add as the options that should be used.

[root@moonstudio ~]# cat /usr/local/sbin/lowlatency
#!/bin/bash

usage() {
cat

Doesn't `apt-get autoremove` remove old kernel versions already? (IIRC it
keeps three? old versions)


Re: the rest, holding back contributions to open source software for money
is pretty poor form. Either contribute, or don't.

Let's see..

There is a script in the archive to help remove old kernels. If I had 
several old kernels installed, I could easily install the byobu package 
and run the purge-old-kernels command.


Now you tell us that you have written a new script to serve the same 
purpose but with some improvements. However, you won't show anybody the 
script unless you get paid enough money in advance. Did I get it right? 
If I did, it's a very odd 'offer' to an open source community.


The cold truth is that you can't make money from the kind of help script 
you have written. People in this community contribute their work all the 
time for free. We contribute our time and skill, and benefit from 
contributions from others.


A few people tried to explain this to you on the ubuntu-doc mailing 
list; this was my concise reply:


https://lists.ubuntu.com/archives/ubuntu-doc/2016-July/020122.html

I'm sorry if someone previously tricked you to believe something else. 
My advice now: Face it and move on.

Another psychotic and unhelpful advice:

[root@moonstudio ~]# apropos mount

IOW instead of pointing from  man mount  and  man fstab  to gvfs,
because users are not willing to learn how to use man pages correctly,
how about suggesting to add missing information to the gvfs man pages,
if the information should be missing?

Do you expect pointers from  man ls  to the GNOME file manager, too?

If a user would take a look at  man mount , then why not also taking a
look at "apropos mount" to see related man pages that are available?

Some of us are editing and reading Wikis, before they spam a mailing
list, just to ignore hints.

https://help.ubuntu.com/community/man

>From the above link:

"It does not cover the tools apropos or whatis, both of which are used
for searching parts of the manpage data, and both of which have
equivalents in man using the -k and -f switches."

So running

[root@moonstudio ~]# man -k mount

does the job, too.

Ralf

Ralf, maybe you should stop telling other people what they should do.

Just saying. That no one needs your advice on what to do, no one is 
asking for it. You don't determine what people are free to do and what 
not, and you are no moderator here.


You are producing a whole lot of noise giving senseless advice to people 
who don't want it in an effort apparently to shut them up or make them 
go elsewhere.


Please quit, as you're not providing helpful advice.
