## Re: (experimental) Alternative usb installation method

Fri Mar 15, 2013 1:20 pm

Script test done. Using yad 0.19.1-1. 2 minor mods made:
line 92: $USBFULLLIST decapitalised
line 308: remove "!" (causes bash errors)
script called with:

Code:
  `su-to-root -X -c 'xterm -hold -e bash -x mklukscrypt'`

Very many errors like this:

Code:
  `(yad:15769): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed
  (yad:15769): Gtk-CRITICAL **: IA__gtk_style_render_icon: assertion `pixbuf != NULL' failed
  (yad:15769): Gtk-WARNING **: Failed to render icon`

Apart from that, everything happend just as expected. Don't know if this log (yad errors cut) is any use in a code box.

## Re: (experimental) Alternative usb installation method

Sat Mar 16, 2013 12:53 pm

I tried your patch this morning, and it worked nicely. Just to make sure I understand correctly, booting with the custom initrd and 'basemountmode=rw,noatime,umask=000' boot options allows me to write to files in /lib/live/mount/medium, but it does not allow me to write to any files inside the squashfs. So it doesn't take the place of persistence, but it could be used if someone wanted to edit their boot menu, for instance, and they didn't have another running linux to plug in the stick and edit the file. I haven't tested this one with persistence yet, but I did it manually a few weeks ago, and it worked.
I've been running the mkusbcrypt script from a root terminal (just "su") separately from refracta2usb. Not sure if I'm going to join them or what.

The actual live-media volume normally gets mounted "ro,noatime" with no way to change.. "basemountmode" is an (experimental) extra parameter to override that, that's all it does. You can't write inside a squashfs under any circumstances.
"umask=000" (VFAT mounts only) allows all-users RW else only root can write
Juggling 2x partitions on smaller devices, e.g. 2GB, is a limitation. This way a persistence loopback file on the same partition can be used, as well as editing of normal files and normal data storage from the live session. The entire free space of the device is available to use.
The patch also includes support for LUKS persistence files, wherever they reside, previously not working. Luks loopback files can be very useful for persistence (or other personal data), they are transferrable, not fs-dependant, can be any size you want and don't require a dedicated partition.
EDIT multiple persistence files can exist, set with " persistence-path=path/to/file" e.g. for multiboot or alt configurations

> I've been running the mkusbcrypt script from a root terminal (just "su")

but yad is graphical, surely root must have "X" authority to use it?

Using 'su' in a terminal allows you to run graphical programs.
Using 'su -' does not.
Starting the root script from within the non-root script is trickier. I didn't try 'su-to-root' yet, because I had trouble with it in the past with the installer and snapshot.

## Re: (experimental) Alternative usb installation method

I failed again.
I had a USB-sd card i used recently.
/dev/sdc1 # a Gig or so
/dev/sdc2 # 3 Gigs or so
Started the script, bash refracta2usb, picked the iso, rebooted.
First i saw the old refracta grub-menu.
It then booted into the right distribution, but to the login-screen (which is wrong, it should autostart the GUI.
I might look at this the wrong way. All i need is a quick way to put a iso to a card or stick.

If grub was installed on the sd card before, you might need to run install-mbr first, or you might need to zero it and make a new partition table. I'm not sure.

What is sdb? Another syslinux or /live could cause a conflict
What distribution? refracta? other Debian? a custom snapshot?
(should be obvious) make sure the machine is set to boot the right device
If grub has been in sd's mbr you do need to clear it manually (install-mbr)

Well: All of that matters?
Using unetbootin i just point it to the iso and am ready to go ...
sdb is the second internal hard-disk.
distribution was crunchbang.
yes, it boots from SD-card
no, i didn't install-mbr

> Well: All of that matters?

It matters to help you get it running and to help improve/debug refracta2usb
One more: what version of refracta2usb? The latest I think uses the menus straight off the iso, older ones had only refracta-specific menu configs, unsuitable for most other debian-live
Take a look in /syslinux on the device and compare it to /isolinux on the iso, it should not be very different (please let us know)
Refracta has a preconfigured live user, most others don't, they need "config" or "live-config" enabled for user-setup and other things.
I won't use unetbootin because I prefer a humanly-readable bash script to someone else's mystical and uneditable binary (WTF is a "ubkernel"?)
