CloudUSB Booting But do not save my inputs.

[Vieira]

Hello People,

CloudUSB is really a very good Idea.

First boot takes a very long time, I had changed password using passwd
command.

After reboot ( lasting too much) password is the same as before
(cloudusb).

and no input remains saved, as firefox preferences, no data remains
persistent.

DO I have to make a special command to save data i have entered?

Ciao from Brazil.

Hi!

I tested the password change via graphical GUI

(System->Preferences->About me in the english version).

the new password is correctly setted on the next reboot.

(I never tested via command line with passwd, but should

work the same way ...)

I usually start the usb key the first time, change the password

and then initialize dropbox, as encfs uses the login

password to encrypt the filesystem.

For Firefox, I tested adding bookmarks, and those are stored

and kept on the following reboot.

The USB key is write enabled (some have an hardware

button to disable writing)?

The key has free space?

You can check with df, and the 

/media/casper-rw should have free space.

If you connect CloudUSB to your dropbox, it

syncronize the data you have on dropbox and

download them to PC: that data could fill the

usb key ...

Just making some hypotesis ... hoping his can help!

Hi Giammy,

Thanks for your answer.

Until now, no way to change password takes effect, after reboot its all the same. (Via GUI).

My Data Traveler Kingston stick 2 Gb has no lock function. If it works Ill buy a big one.

I am receiving an error window just after login has finished saying:   gvfsd-metadata closed unexpectedly

About Space, what do you notice in this display? (but there in no casper-rw )

I dont want to setup dropbox for now. But I want to save my input.

See the Fdisk display:

Interesting, /dev/sda1 is remount-ro

Interesting, Boot process is trying to read diskette.

Now Ive disconnected all HD and diskette and DvD drive is empty. I think boot is more fast.

I am answering to these EMails using CloudUSB.

I wish I could use CloudUSB for many Things.

Grazie tanti


Um forte abraço,

2Gb should be enough.

The gvfsd-metadata closed unexpectedly

is an error I saw, but I did not find how to remove.
In a persistent configuration it will show just the 1st boot.

The problem, as you pointed out is that there's no casper-rw.
To create the key I used tutorials found on the web
(here an example)
http://www.debuntu.org/how-to-install-ubuntu-linux-on-usb-bar

In particular, the casper-rw partition must exist: that is,
there must be a partition to write data to (to have the
persistent feature) and that partition must have the
casper-rw label

When I create the usb key (script create-usb-key_1.1.sh the relevant part is:

debug "Formatting partition (1) ..."
umount ${SELECTEDDISK}1 2>/dev/null
mkfs.vfat ${SELECTEDDISK}1 | (zenity --title "Formatting ..." --text "Formatting ${SELECTEDDISK}1 ..." --progress --pulsate --auto-close)

(partition for the operating system)

debug "Formatting partition (2) ..."
umount ${SELECTEDDISK}2 2>/dev/null
mkfs.ext2 -b 4096 -L casper-rw ${SELECTEDDISK}2 | (zenity --title "Formatting ..." --text "Formatting ${SELECTEDDISK}2 ..." --progress --pulsate --auto-close)

and this is the partition for the persistent data: note the "-L casper-rw" option.
That option is needed.
in the usb key both partition must be present: you probably
have the 2 partition, but the second has not the label casper-rw.
(this is present in the script create-usb-key_1.1.sh at line 177)

On the running system you need to have a /media/casper-rw
otherwise it will not be persistent.

By the way, another critical point to have the persistent configuration is:

sed -i 's/append initrd=\/ubninit file=\/cdrom\/preseed\/custom.seed boot=casper quiet splash --/append initrd=\/ubninit file=\/cdrom\/preseed\/custom.seed boot=casper persistent quiet splash --/g' /media/usbkey/syslinux.cfg

that is the boot option in syslinux.cfg must be
boot=casper persistent quiet splash --

while the default is:
boot=casper quiet splash --

In your key, in file /syslinux.cfg there's the persistent option?

this is present in the script create-usb-key_1.1.sh at line 192.

Hope this helps (and thanks for the very good description of your problem,
with all the commands output!)

buona giornata!

Hi Giammy,

Today I've bought a new 4Gb stick. I ran create... script as I made on saturday, and everything is working.

I didn't run setup script as before. But now my data is persistent.

The problem is that I have a friend ( poor girl), she received as a Gift an old toshiba notebook but after 1 mount of using it the "IDE"  Hard Drive doesnt work anymore.

I gave her a "Parted Magic" Live CD an she is using firefox to browse Emails, but she cant play a video, and more...

Now I can set up a very good Linux for her, Browsing and playing everything...  Thats the aim of my research.

But help me understand something:

     First partition is 1,5 Gb and it has the CloudUSB image.

     Second partition i 2.5 Gb and is persistent.

     If I install some sotware like VLC or Ubuntu-Extras, this software will be on first or second partition (second I guess so),

     What is the link for old and New software???

     If I save something in Documents User folder will it be persistent???

Thats all for now, and many many thanks for your answers and explanations.

Grazie mille,

Buona sera


Um forte abraço,

Vieira

yes: the 1st partition will keep the preinstalled software.
All the new software, personal documents go
on the second partition.

>      What is the link for old and New software???

the new installed software? you call it from command line
of from gui as normal.

If you need to personalize with various software, you
can get a look at the script
http://cloudusb.net/files/cloudusb-build_1.1.sh

This is the script I used to create the cloudusb ISO.
From your messages, i understand you have some
expertise in IT, so I think you should have no problem.
(essentially, you start from a clean system, install
and update all you need, then create the iso).

The advantage is that in this way you build a personalized
cloudusb with all the software your friend needs, and
she can use all the second partition for her data.
