Out of curiosity, what real-life uses does this tool have? Daemons don't
need to be reniced, so there must be something else.
Actually, I wonder if this really warrants a package on its own; AFAICS
it just adds some sugar and error checking to something as basic as
,[ reniced.sh ]
| #!/bin/bash
| grep -v '^#' ${1:-$HOME/.reniced |
| while read prio regex; do
| renice $prio $(pgrep $regex)

Re: Bug#381201: ITP: reniced -- renice running processes based on regular expressions
Of course, the problem is that gcc spawns many processes, and if reniced only takes a little while to react to a new gcc process, the children won't be reniced. If I understand correctly the description, reniced is not actually a daemon but a program that you run from time to time, so not really usable for this purpose. -- Zorglub -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Out of curiosity, what real-life uses does this tool have? Daemons don't need to be reniced, so there must be something else. Why don't daemons need to be reniced? I have a rather slow system here (Cyrix 100MHz, 64MB RAM) that runs some server processes like exim, inn2, spamassassin etc. News for example is no realtime application so I want my inn2 to run with a certain nice value. I don't know of an INN configuration value that sets this level. So my first approach was to edit /etc/init.d/inn2 and insert a renice 5 $$ somewhere in the script. This makes updates a hassle because I've edited a configuration file. On the other hand, I've got a remote MP3-player that is powered by a server process slimserver which runs under my user account. To avoid skips I like to run it with a negative nice value. I'd need root priviledges to set these values so I'd have to run a wrapper using sudo or something. To address both of these scenarios I've written reniced. It runs daily, has the needed root priviledges and does everything as needed. I've attached my current configuration to this mail, perhaps this gives you an idea what I'm up to :-) The best solution IMHO would be to add an optional nice value to /etc/default/package and let this be used in every script in /etc/init.d. I think some packages already do this, but changing every package would need some work (I don't know if this feature is needed by someone else besides me).

This is about daemons that are not designed to be configured in that way. The easiest solution was to just add a line to the /etc/init.d script. A better way would be to add a nice configuration value to either every daemon (lots of work upstream) or at least to the init scripts (still lots of work, but start-stop-daemon already has an --nicelevel option).
