Depends on the amount of information you display.
Not every detail like which kernel, etc.
If you quickly see wrong things, like an unusual size,
it can be helpful. If your qtmoko partition will
be of 1000GB size, you would probably abort.

Or you can print model name of the device.

So just enough information to ring alarm bells but
not too much that you do not see critical things

Maybe that confirmation will be only enabled if
.makesd.conf is not available. So it does not break
you mass-production of production-test sdcards.

Regards,
Andreas

Well, it has to have some default because if you make 20 sd cards
per day, every keystroke counts. And in 19 times you type
/dev/sdg correctly and then you mistype /dev/sdh + Enter.

So it needs some default you do not have to think about too much.

There is already a secondary default which reads the file ~/.makesd.conf
to set such a default. And the /dev/sdc is only used if that file
does not exist or is empty.

I have already updated the documentation page because that
feature is available for a while.

And we can simply replace the final /dev/sdc default by /dev/null...

Oh, sorry.

It was warned in the description to take care, but that hint doesn't help
of course if it is too late. It may help others reading this mail.

I hope you have a backup.

No,
if you call fdisk you see what disk you use.
Here Sven thought, makesd would access /dev/sdg
but did access /dev/sdc!

That is a different thing.
fdisk does not do any writes when it is called without a device name to
work on!
makesd does.

Sven's sudo construction is just equal to calling
makesd *without* DEV set!!!

In that case makesd should not take a predefined device.

Maybe makesd also should display a list what it wants to do
asking for final confirmation

The best thing would be to call makesd from NAND with a graphical
interface.

No, that would not work, because you want to mount the device and
create device nodes on it, which would require root privileges again.

Ah, ok. Well, it seems to protect the user :)

I usually use an SD card reader of some SBC where I did ssh root access to so I 
never thought
about needing sudo.

Maybe we should add a check that you really have write access to the specified 
device.

That is a harmless and known bug. The script is not completely checking 
everything. So these warnings are not prevented.

Well, it is impossible to perfectly prevent erasing the wrong device, because 
only the user can know what the SD card reader with an SD really is.
So it is equally risky as calling fdisk directly.

There is at least one protection: you can't overwrite /dev/sda.

What you could do is to just sudo chmod o+rw /dev/your-sd-reader
but I am not sure what happens with newly created partitions.

> 
> Furthermore: Why "fsck.ext2"? My QtMoko v55 and v57 SD cards had already been

No idea. The script only calls fsck.ext3. Seems to be a bug in util-linux 
2.27.1 when printing the error message.
On my system, there are symlinks:

root@letux:~# ls -l /sbin/fsck.ext*
lrwxrwxrwx 1 root root 6 Dec 31  2016 /sbin/fsck.ext2 -> e2fsck
lrwxrwxrwx 1 root root 6 Dec 31  2016 /sbin/fsck.ext3 -> e2fsck
lrwxrwxrwx 1 root root 6 Dec 31  2016 /sbin/fsck.ext4 -> e2fsck
lrwxrwxrwx 1 root root 6 Dec 31  2016 /sbin/fsck.ext4dev -> e2fsck
root@letux:~# 

which means they are all the same independently of the ext2/3/4 suffix... One 
size fits all :)

Anyways, this is just a safety check for a freshly created partition. So it 
should normally pass and
does not need to be perfect. It fails only if you have a broken SD card or SD 
card reader which
pretends to have written data...

So I will prepare patches for both issues reported above. They will be 
available in some
days (after I have tested them).

Thanks for feedback about makesd. It can only become better :)

Nikolaus

Hi Sven,

Reason is probably:

sudo does not pass the variables on (security reasons,
you could do funny things).
So makesd did not know about your DEV=/dev/sdg

makesd should simply have no default for DEV
and not do anything if not set.

Andreas

if there's something that you'll learn very soon in IT, then the fact that 
everything will take much more longer than expected...

For me your one simple makesd-line resulted in the following:

1.) Assumed that my some years old makesd is completely outdated. So 
searched for a current one and found:

http://projects.goldelico.com/p/gta04-makesd/

Thus did the folowing actions:

wget -O makesd "
http://git.goldelico.com/?p=gta04-makesd.git;a=blob_plain;hb=HEAD;f=makesd
"
chmod a+x makesd
./makesd -u

Success! Ok, that was easy.

2.) Clean the SD card with the v55 clone completely:

sudo dd of=/dev/sdg if=/dev/zero bs=1M conv=fsync

After that all the partitions have been gone. Again easy success.

3.) Execute your suggestion:

DEV=/dev/sdg makesd qtmoko -r 
http://download.goldelico.com/letux-debian-rootfs/20180224-wheezy-7.11-armhf-qtmoko.tbz

Result: "Command makesd not found".

Ok, that's understandable. So modify your suggestion to:

DEV=/dev/sdg ./makesd qtmoko -r 
http://download.goldelico.com/letux-debian-rootfs/20180224-wheezy-7.11-armhf-qtmoko.tbz

Result:

unknown option: -r 
http://download.goldelico.com/letux-debian-rootfs/20180224-wheezy-7.11-armhf-qtmoko.tbz
useage:...
...
root file system (OS):
-r 
...
-r qtmoko
...
macros for single partition cards:
...
qtmoko = -f ext4 -r qtmoko -d all -k latest (does not need config)
...

Please advice ...;-)

Best regards
   Sven

Dear tinkerers and readers,
it is time for another update:

* we have brought the Jessie and Wheezy source code in better sync [1]
* in total we currently have just 5 patches on top of Wheezy
  to get it compiled and linked and installed on Jessie
* we have fixed some wrong ALSA mixer states
* some (invisible) warnings have been fixed - just to be safe
* there is a script for easier debugging on the device (it runs qpe
  under the control of gdb and disables auto-suspend)
* Andreas has found some more power-saving patches for the kernel

The Jessie version has a significant bug (a double-free) where we
only know that it comes from QSmoothListPrivate::dereferenceItem
called by libQtCore.so.4 while closing e.g. the Calendar.

This seems to be very difficult to track down since the first free()
must have been done unnoticed much earlier in code.

And it is not at all obvious how this comes from compiling on Jessie
and adding 5 patches. It might be a gcc bug, or a bug that reveals
itself only when using a newer gcc or newer APIs of some libs.

This means at the moment we can only recommend to use the Wheezy
version. Unless we can fix that in source code.

Finally, I have installed QtMoko/Wheezy through makesd on an
OpenPandora SD card and the result is promising:

So it might at least basically work at on the PyraPhone as well.

BR and happy tinkering,
Nikolaus
