That is no error, and you don't want to fix it. Many processes do fork into multiple instances.

Oh really? I see. This doesn't happen on Linux though. Like Ubuntu and Debian. Can you explain technically what actually happens with these forks and its purpose?
Im still curious to know if I could delete everything in root and be able to flash, or some sort of super flash to wipe out every single thing. Cos im pretty sure, a flash does not completely replace everything.
I've done a lotta flashing between OS2008, OS2007, and some Dev version, and theres always little bits of pieces left behind from the previous flash. So I always feel a bit dirty after each flash. I want squeeky clean! I thought this way cos of the duplicate processes, but since you say that it's normal, then I guess flashing reformats well enough.
Would still like to know about removing root though.
Thanks for the quick response.

Of course it does happen on Linux, and anywhere else for trhat matter - forking/IPC or threading are the standard way of handling asynchronous tasks in a multitasking environment.
YMMV whether it becomes obvious. There is no great difference process wise between threading and forking in Linux, the visibility of threads and forked processes depends on the threading model (on Linux threads, threads were processes in every aspect, NPTL changed that somewhat), and the version of ps/top you use (the busybox variants used on the IT make no effort to merge threads and forks, while some graphical process viewers will - erroneously - even recombine separately started instances into one process) and the arguments you call them with.

Ahh I see even more. I guess the 'ps' on my Ubuntu is hiding those thread/fork information. Good to know.
Thank you.
Oh by the way, something unrelated.
In date&time, you can't pick Perth, Australia as home city.
There are:
Sydney, Australia
Melbourne, Australia
Canberra, Australia
But no god damn Perth!!! It's in Western Australia. There is a city on the West too! The desert is in the middle!
Where should I be taking this complain to? Nokia? Maemo?
Oh heres a forum-based thank you too.

My suspicion for " little bits of pieces left behind from the previous flash" was mainly due to the duplicate processes, which sevo has already explained that it is normal.
My other suspicions were from reading other people's complaints of their device not performing the way they used to even after clean reflash. Slow browsing and all.
Then there are complaints of background processes which are silently draining battery while off or idle.
Then this thread, http://www.internettablettalk.com/fo...d.php?p=118288
And whole bunch of other little threads saying flashing aint helping.
Then I found out about the duplicate processes on MY device and I've been experiencing slowless in OS2008 compared to OS2007 possibly due to the multiple duplicate processes. I was convinced that flash does not erase things properly.
Now that sevo has cleared things up, I guess I was paranoid. So flash should be doing what it's supposed to. Unless someone pops up and says otherwise.

Here's the instructions I used to add a new timezone (was easier for me because I could just follow them being in Adelaide as well - you'll have to find the pixel offset yourself). I couldn't follow the second part (cloc_db_city_Adelaide bit) because the file wasn't there, but it seems to work fine without it.

Oh and Adelaide, Australia isn't included too.
Thanks for the fix.
But OS2008 (and previous versions) needs you to manually adjust the time anyway. The point of choosing your city and country is so that the time will automatically set and sync itself with NTP or something, which it doesn't.
Oh I still wanna know if I could rm -R / without bricking the system.

Doing an "rm -R /" will wipe out the kernel files needed to start up the system as well as all supporting files.
There are duplicate proccess of the same process running.

So is it a good idea to manually remove the whole filesystem in the terminal like this?
rm -R /
Then be able to boot up the N800 and flash it as instructed here http://maemo.org/community/wiki/howt...magewithlinux/ ?
