*-rw persistence mode and disk images
Hi list,
this is mostly for mammadori,
--
16:50 < aym3ric> mammadori: we haven't found a way to make it work with
files yet though, only named partitions are recognised correctly
16:51 < aym3ric> mammadori: using an ext3 formatted file, ends up in a
nice ASCII debian logo and a suggestion to send a boot log
[...]
17:28 < mammadori> aym3ric: mail to ml the pastebin since it is expired
please
--
More details
- we used live-initramfs_20081007-1_all.deb (made locally from git
checkout of the same day)
- persistence has been tested booting the live image from a HD (live
folder on the root of partition, grub entry to load it, etc.)
- partition based named rw persistence works perfectly fine (home and live)
- the same using a disk image instead of a partition is failing during
the boot process. debug log attached.
- the liveCD config can be found here:
http://code.goto10.org/projects/puredyne/browser/live/config
About the disk image:
It was located at the root of an empty ext3 partition (no name) of
the same disk that contained the live folder. It was generated using this:
#/bin/bash
#quick home-rw image
SIZE_4k=`expr \( 100 \* 1000 \) / 4`
dd if=/dev/zero of=home-rw bs=4k count=$SIZE_4k
mkfs.ext3 -F -j -L "pure:dyne" home-rw
congratulations for this great project btw :)
Hope this helps, let me know if you need further details
Hopefully we're not doing something obviously stupid here ...
