Hi, how do I set-up bootchart? I have a genkernel based kernel so init is init=/linuxrc, I have tried the /sbin/bootchartd and modified the /etc/conf.d/rc file but I still can't make it start on boot (I can run it after login. Do I have to do something else?

sometimes you need to create the folder /var/log/bootchart.
I had to do it cos without it didnt start

sorry but I don't get it  do you have it or not? if you don't have it, bootchart cannot create .lock file and something else (don't remeber what). in this case create it.
of course the result will be in /var/log.

the directory /var/log/bootchart with a .keep file in it exists.
I found a bootchart.tgz file in my /var/log though but I think it's the one that I created when I ran /sbin/bootchartd start as the chart indicated services already started.
Thx for the interest. |

ok let's start from the beginning. I did such things
1. emerge bootchart (there is an ebuild on bugs.gentoo.org I think)
2. add | Code: | | RC_USE_BOOTCHART="yes" |
to /etc/conf.d/rc
3. add init=/sbin/bootchartd to grub
the only things which we have different is that I don't have initrd.

Perhaps bootchart doesn't work well with genkernel kernels?
Can there be two init=/asdasd entires in the kernel param? is init=/linuxrc necessary? |

maybe i'm wrong but AFAIK standard is init=/sbin/init. I don't think that it's possible to have two init=...
for example bootchart by default starts init. if you want to change it to e.g. initng but still to use bootchart, you need edit bootchart script (/sbin/bootchartd) and replace init by initng.
I don't know what are the differences between genkernel versions and manual versions cos I have never used genkernel.
just check if it is gonna boot without initrd and all other stuff i.e., put in grub such option | Code: | title=Gentoo Rocks

Has anyone ever found a solution for this? I recently installed initng and tried to get bootchart to work to see what is actually happening during boot, but I seem to have the same problem.
I emerged bootchart, added RC_USE_BOOTCHART="yes" to /etc/conf.d/rc, edited the bootchartd to start initng instead of init, and edited the grub.conf to show init=/sbin/bootchartd, yet upon boot, not initng is started, instead it seems to be defaulting to init. All there is in the /var/log/bootchart directory is an empty .keep file.
Right before init is executed, a brief message is displayed saying something like "/dev/null cannot be found". Looking at the bootchart code, this is where the tmpfs is mounted. It seems that the problem is there somewhere...
Any ideas?

That was one of the first attempts I made. No joy whatsoever...

I finally got it to work, and as usual, it was the most obvious that I overlooked. The script /sbin/bootchartd (or /sbin/bootchartdng) needs to be executable.

Will bootchart be added in the portage someday?

You will need to somehow add bootchartd to your initrd I guess... |
