Aug 18 23:32:07 <PhotoJim> so... Debian on a Sheeva.  Wanting to move / from a partition on the USB hard disk to SD.  I should just be able to partition/format the SD card, make the correct SD partition bootable, rsync / (less the system directory contents like /dev and /proc and such of course) and change the boot parameters and all should be good, correct?
Aug 18 23:32:20 <kerio> yep
Aug 18 23:32:28 <kerio> although it's *incredibly* awkward to do with a running system
Aug 18 23:32:36 <kerio> you should boot off something else
Aug 18 23:32:46 <Tootoot222> PhotoJim: you don't even need to set the bootable flag
Aug 18 23:32:53 <Tootoot222> you just tell uboot to use the sd card instead of the usb
Aug 18 23:33:03 <kerio> PhotoJim: oh yeah, the bootable flag is a relic of an ancient past
Aug 18 23:33:05 <kerio> ish
Aug 18 23:33:16 <kerio> regardless, it's not needed with uboot :)
Aug 18 23:33:23 <PhotoJim> that was a very quick and informative response given the silence.  Heh.
Aug 18 23:33:37 <kerio> PhotoJim: do you still have the original ubuntu system on the NAND?
Aug 18 23:33:45 <kerio> boot that, and do your move from there
Aug 18 23:33:46 <PhotoJim> I haven't touched it.
Aug 18 23:33:56 <PhotoJim> I've just ignored it.
Aug 18 23:33:57 <kerio> otherwise you'd have to remount the rootfs as read-only to copy it
Aug 18 23:34:02 <kerio> ...wait, i'm being silly
Aug 18 23:34:06 <kerio> just use a different computer
Aug 18 23:34:09 <Tootoot222> or you could like
Aug 18 23:34:10 <Tootoot222> yeah
Aug 18 23:34:12 <kerio> :D
Aug 18 23:34:13 <Tootoot222> just do it on your laptop
Aug 18 23:34:27 <kerio> i like my sheevaplug to be self-sufficient
Aug 18 23:34:32 <PhotoJim> my netbook has SD slots (2 in fact) so that'd be the easiest place.
Aug 18 23:34:47 <PhotoJim> I want to do this for the disk space.  Sheeva is my offsite backup box.  and I need the entire USB drive for the purpose now.
Aug 18 23:34:48 <kerio> PhotoJim: you'll have to tinker a bit with uboot though
Aug 18 23:34:52 <PhotoJim> yes.
Aug 18 23:35:00 <kerio> booting off something that's not the NAND is always a bit flaky
Aug 18 23:35:02 <PhotoJim> I have another Sheeva at home booting off SD.  so I just need to replicate its uboot config.
Aug 18 23:35:11 <kerio> can you put the kernel on the NAND?
Aug 18 23:35:14 <PhotoJim> I'd rather use SD than the NAND.
Aug 18 23:35:15 <kerio> that usually solves most of the problems
Aug 18 23:35:26 <Tootoot222> kernel on nand is best
Aug 18 23:35:27 <PhotoJim> if I wear out an SD card, they're trivial to replace.
Aug 18 23:35:35 <Tootoot222> PhotoJim: you only wear out the nand by writing to it
Aug 18 23:35:48 <Tootoot222> it's got like 10000 writes or something per block (of 256 bytes)
Aug 18 23:35:51 <PhotoJim> I think kernel on NAND is compulsory anyway isn't it?  e.g. flash-kernel in Debian
Aug 18 23:36:17 <kerio> you'll probably wear out your skull before your sheevaplug's NAND
Aug 18 23:36:22 <kerio> PhotoJim: i'd actually uninstall anything related to the kernel
Aug 18 23:36:36 <kerio> and use the xilka kernel
Aug 18 23:37:02 <Tootoot222> PhotoJim: no, you can make it load from anything
Aug 18 23:37:11 <Tootoot222> you just have to load it into memory at 0x800000 or whatever
Aug 18 23:37:13 <Tootoot222> then boot
Aug 18 23:37:19 <Tootoot222> you can use tftp, usb, sd, whatever
Aug 18 23:37:27 <PhotoJim> First I've heard of Xilka.
Aug 18 23:37:36 <kerio> bash <( curl http://www.xilka.com/sheeva/UPDATE-SHEEVA-KERNEL.sh ) --nandkernel 3.5.2
Aug 18 23:37:54 <kerio> PhotoJim: used to be sheeva.with-linux.com
Aug 18 23:37:57 <PhotoJim> ahh.
Aug 18 23:37:58 <Tootoot222> aha
Aug 18 23:37:58 <kerio> http://www.xilka.com/sheeva/
Aug 18 23:38:18 <PhotoJim> so is it to Sheeva what Raspbian is to Raspberry Pi then?
Aug 18 23:38:28 <PhotoJim> i.e. customized Debianish distro specifically for that device
Aug 18 23:38:33 <kerio> nah, i only use the kernel
Aug 18 23:38:40 <Tootoot222> it's just a general purpose kernel
Aug 18 23:38:45 <kerio> standard debian works fine, this is not an embedded device :)
Aug 18 23:38:50 <kerio> well, not *that* embedded, at least
Aug 18 23:38:58 <PhotoJim> I've just been using the standard kernel.
Aug 18 23:39:23 <kerio> this is standard too, but doesn't autoupdate with apt - which is good, for a kernel - and is custom-made for *plugs
Aug 18 23:39:26 <PhotoJim> which is 2.6.32-5 so fairly old.
Aug 18 23:39:39 <PhotoJim> I'll check it out.
Aug 18 23:39:41 <kerio> heh, my n900 still has 2.6.28
Aug 18 23:40:33 <Tootoot222> my plugs are all running pretty old kernels
Aug 18 23:40:36 <Tootoot222> i haven't updated in months
Aug 18 23:40:43 <Tootoot222> $ uname -r
Aug 18 23:40:43 <Tootoot222> 3.0.0-gentoo-toot2
Aug 18 23:40:47 <Tootoot222> yeah
Aug 18 23:40:49 <Tootoot222> i should probably update that soon
Aug 18 23:41:13 <kerio> PhotoJim: it's a neat script, it flashes the kernel (so it's only on nand, not also on the rootfs - not sure if you'll like that) and downloads the modules
Aug 18 23:41:32 <kerio> if you're *that* worried about wearing off the NAND, you could even tell uboot to ext2load or fatload the kernel for you
Aug 18 23:42:42 <PhotoJim> not that worried.  :)
Aug 18 23:42:47 <PhotoJim> wouldn't want to run rootfs on NAND though.
Aug 18 23:43:06 <kerio> i am
Aug 18 23:43:11 <kerio> ubifs is the shit
Aug 18 23:43:15 <PhotoJim> Heh.
Aug 18 23:44:45 <Tootoot222> i put / on the nand
Aug 18 23:45:06 <Tootoot222> but the portage tree is too big to fit, so i put /usr, /var, and /home on an esata drive on my dreamplug
Aug 18 23:45:26 <Tootoot222> hardly anything gets written to the nand itself
Aug 18 23:45:30 <Tootoot222> but it still boots up quickly
Aug 18 23:45:55 <PhotoJim> ahh, you're running Gentoo.
Aug 18 23:46:19 <PhotoJim> yes, that would work okay.  not a lot of writing to NAND.
Aug 18 23:46:23 <PhotoJim> I need to run.  will check in later.
Aug 18 23:46:26 <PhotoJim> thanks for the help guys.
Aug 18 23:47:15 <Tootoot222> np
Aug 18 23:48:04 <kerio> =D
Aug 18 23:53:05 <tinker-f595> it is really easy to boot completely from sd card or a usb device
Aug 18 23:53:49 <Tootoot222> sure
Aug 18 23:54:02 <Tootoot222> you just use ext2load instead of nand read
