Well, since PR1.2, Maemo gets into an infinite reboot loop when it can't mount /home. The method involves moving /home. If you mess up the entries in genfstab.awk and/or rcs_late, or maybe the copy of the home directory, it could be that Maemo can't mount home, resulting in a 'bricked' device.

Though bricked isn't the correct word here, as the phone can be revived by reflashing it. So no: it can't be bricked and yes: if something goes wrong, you'll have to reflash*

I don't know about your linux knowledge, but if you understand the commands involved, it should be safe to execute them.

*While trying out different partition configurations, I've messed up once too, causing Maemo to be unable to mount /home resulting in a reboot loop, but a reflash solved this.

Edit: I've added an extra warning to the wiki entry

You just need to adjust the partition table to make /home bigger and MyDocs smaller.

You will lose the content of MyDocs, but that folder is easy to backup (copy 'n paste). All your settings etc will be kept.
Please note I've applied that method to a cleanly PR1.3 reflashed device, though the method should work on a 'dirty' device as well.

Also possible: full eMMC as ext3 /home (with MyDocs as loopback file) + MicroSD as swap =

Great news! I want to try it!

But I have 2 questions about it:

a) After bricking your N900, did you try MeeGo Rescue Initrd? Doesn't it work?

b) Can you post the table for 6GB /home and 23 GB MyDocs?

Thanks

No I haven't. I had nothing to lose as I started repartitioning on a empty (reflashed) device, so reflashing it again after messing up would be easier than recovering it.

Code:

unit: sectors
/dev/mmcblk0p1 : start=       64, size= 48242688, Id=c
/dev/mmcblk0p2 : start= 48242752, size= 12582912, Id=83
/dev/mmcblk0p3 : start= 60825664, size=  1572864, Id=82
/dev/mmcblk0p4 : start=        0, size=        0, Id=0

This wil give a ~24GB /dev/mmcblk0p1, a ~6GB /dev/mmcblk0p2 and the default 768MB /dev/mmcblk0p3

how i can edit genfstab.awk?

i am in this step:
-Open /usr/lib/genfstab.awk and comment out the following pieces of code

Code:

start == 1 && $6 == 83 && !__home { printf "%s /home ext3 %s 0 0\n", $1, home_opts printf "/home/opt /opt none bind\n" __home++ }

Code:

start == 1 && $6 == "c" && !__fat { printf "%s /home/user/MyDocs vfat %s 0 0\n", $1, fat_opts __fat++ }

Using an texteditor like vi, nano* or even leafpad. Run those from a root terminal:
Nokia-N900:~$ root
Nokia-N900:~# nano /usr/lib/genfstab.awk

However, I have to ask: do you know what you're doing? As editing a file is pretty basic stuff, while partitioning can be rather risky when not done right.

*watch out using nano-opt from the repos, it spreads lines that don't fit the width of the terminal window out over two different lines (word wrap), causing a malformed file when not fixed.

Yes, you can boot NITdroid or Ubuntu from internal memory!
I moved the NITdroid folders to /home and multibooted it from /dev/mmcblk0p2. i mostly prefer using easy debian to use ubuntu 10.10 apps and desktop from 5gb /dev/mmcblk0p4, some people are able to boot into it (may be phone is ready to use soon). There is no limitation having a quad or more booting N900 with meego (but it's really slow on my sdhc).

And just a question: do you guys envisage a future where it would be possible to repartition the internal memory so as to install other OSs in it? Say, NITDroid? Has anybody tried it? Is it possible as of today? Would multi-boot work on such a partition scheme?

Once again, thank you for all the effort you guys have been putting into this (ruskie, titan, guy with the chinese name I couldn't possibly type on my lowly western keyboard, and all the others. Far out!).

i followed all steps 2 times, and 2 times my phone continue with 2GB in /home.
when i reboot my phone use MicroSD how a /home, and i format /home and /MyDocs, and i reboot, all correctly, but when i finished i check memory and MyDocs said 27GB and /home *free 1,6GB*

in this step:

Code:

-Open /usr/lib/genfstab.awk and comment out the following pieces of code
Code:

start == 1 && $6 == 83 && !__home {
       printf "%s /home ext3 %s 0 0\n", $1, home_opts            
        printf "/home/opt /opt none bind\n"
        __home++
}

Code:

start == 1 && $6 == "c" && !__fat {
       printf "%s /home/user/MyDocs vfat %s 0 0\n", $1, fat_opts
       __fat++
}

I have to do? i check the file and is exactly how code...

he means by * comment out *? delete?
