Subject description: read-only filesystem
 

Dear Developers!

I wrote the easy os 2.3 to usb flash drive with easy dd. Now the system is running from this flesh drive. I want to copy data from an external storage to my computer's internal drive, but I get the error message that the file system is read-only. You could help what the solution might be.
Lenovo iodepad 520, i5-8250, 8 GB ram, 240 GB ssd.

Version 2.3.1 is out:

Some earlier posts in this forum thread have reported some problems that I have not yet got around to.

Hi, I didn’t read it all.

But I see the following problems:

- At startup the copy of puppy sfs in ram is very long.
- There are duplicate icons on the desk
- There are significant delays in operation
- Gxmessage happy puppy works on its own

See my capture.

Good day

This might be better than installing cdrkit in addition to the already included cdrtools or even Debian's genisoimage Buster package (Debian have split up cdrkit into separate packages as they often do).

@ Barry

Hi Barry,

thank you for the Win10 installation report which just seems to be another example which gives insight into the well-known Microsoft mentality.

Do you have an explanation for the fact that your unintended Easydd command left untouched partition 4 on the NVME drive?

kind regards

PostPosted: Mon 08 Jun 2020, 16:00    Post subject: Easypup 2.3.1
Subject description: observations
 

@ Barry

Hi Barry,

aware that you did not promise full support for Easypup, I tested some features of Easypup 2.3.1 and would like to mention the following observations:

At bootup, Easypup 2.3.1 spontaneously offers to load save files of previous frugal Easypup installations (e.g. easypup 2.14; easypup 2.16), apart from a 0 (zero) option.

There is no Easydd icon in the Menu-list.

Right mouse button-klicking onto an *.img.gz or *.iso file results in an error message (screenshot 1), but a functional Easydd GUI can be launched via sakura (screenshot 2).

This GUI seems to be equivalent to the EasyOS 2.3.1 Easydd GUI despite looking somewhat differently (screenshot 3).

The Gparted and the fdisk information about the boot drive (sdb; external IDE HD) are showing confusing differences (e.g. MB/GB per partition). The boot drive (prepared via Easydd) has an MBR as well as a GPT partition table (hybrid iso partition). (screenshots 4 and 5)

The drive icons sdb1 and sdb2 prove to be inversed, as compared to EasyOS standard (screenshot 6).

Deleting the GPT does not seem to affect the funtionality of Easypup 2.3.1.

At first shutdown Easypup 2.3.1 offers misleading save options and wrong information. (scrennshots 7; sceenshot Cool


kind regards

EDIT 1:

To additionally illustrate the above observations, I add screenshots 9 and 10

Note that they will appear on the top of the previously listed screenshots!


[b]EDIT 2:

Sorry, I just now realise that this report does not belong here. I missed the forum and will post it to the (appropriate) Easypup forum

Just tried your suggestion of using the above script file from DpupStretch. It works great. Much smaller and better solution than installing genisoimage which is 620k.

Now Barry needs to see this so he can see there was a need for this in Dpup and hence fix his official version of EasyOS and Easypup. I have come to the conclusion that not many people are using Peasydic or for that mater, optical media. Peasydisc has been failing for a long time ever since the EasyOS switch was made from Ubuntu to Debian packages and nobody seemed to notice. I generally don't like to post, I'm over 80 years of age and I just sit back and let the young guys solve the problems. So, when Barry said he was ready to finalize EasyOS 2.3, I just had to say something. I had 4 issues that were not being address and this was one of them.
Thanks for your help.

You can probably get the same result just by using a symlink.
Code:
ln -sf /usr/bin/mkisofs /usr/bin/genisoimage

The EasyOS image file is 1.3GB expanded, so this only overwrote the first 1.3GB of the NVME drive.

Partition-4 is 1GB at the end of the drive, so was left untouched. As was the GPT at the end of the drive. By using the 'gdisk' utility, I was able to recover the primary GPT from the backup GPT at end of drive, then partitions-1 to -4 were recognised, except that 1-3 were wreaked.

There is a new Chromium SFS:

https://bkhome.org/news/202006/chromium-sfs-8003987162-created.html

Regarding my blog post about booting Win10 off a usb-stick, and not working because it a udf filesystem in the iso:

https://bkhome.org/news/202006/how-to-boot-win10-from-a-usb-stick.html

So how come the iso boots from optical media? Wouldn't the UEFI-firmware have the same non-recognition of udf problem?

When googling around, didn't read any reports of people not being able to boot, once they had obtained a double-layer dvd and burnt to it. But, I haven't tried it myself.

@ Barry

Hi Barry,

Thank you for your explanation!

I understood the steps which you described in your Win10 installation report, but I was surprised that Easydd does not 'eliminate' all data on the target drive, by default.

Am I right to suppose that the Easydd command does not result in a really pristine installation of *.img.gz or *.iso files on previously populated drives and that, to reach this latter goal, before running Easydd, 'zeroing' of the drive would be required.

This might be a security measure which always should be taken into account.

kind regards

Well, it would be good to eliminate the GPT at the end of the drive, so that the old partition information cannot be recovered.

In my case with the accidental write to the nmve drive, it is good that the backup GPT was still there, however, normally it would be better to eliminate it.

it would be easy enough to write a certain number of zeroes to the physical end of the drive, to get rid of that backup GPT. I could add that to easydd.

That's if the flash stick uses GPTs, most don't, they are, I think, just MBR partitions, where partition tables are only at the beginning of the drive.

EasyOS image is also just a MBR.

EDIT:
Sorry, I replied too hastily. The EasyOS image file is two partitions, a 639MB fat32, and a 640MB ext4. At first bootup, the ext4 partition is expanded to fill the drive. If there was a pre-existing GPT at end of drive, it would get overwritten -- the MBR system does not know anything about GPT and the partition and ext4 filesystem would get created right to end of the drive. Any pre-existing partitions would no longer exist.

I think it would be just about impossible to recover any information from those pre-existing partitions, so I don't think there is any reason to erase the drive beforehand.

Subject description: partitions MBR GPT
 

@Barry,

Hi Barry,

Thank you also for your EDIT! I highly appreciate your support!

Running EasyOS 2.3.1 (as, previously, after installing it onto the external IDE HD via Easydd), I again checked the partition informations (GParted, fdisk, gdisk).

To my surprise, and in contrast to your EDIT, gdisk still mentions a 'secondary partition table' and an overlap of this 'end of drive gpt(?)' with the expanded ext4 partition (?), after first stating 'gpt not present'! Just a confusion of the gpt-tool?
See screenshots 1 and 2.

Sorry for potentially causing additional trouble! It's not my intention to annoy unnecessarily!

kind regards

Yes, linking mkisofs to genisoimage work fine and also solves my problem.

Parts of Peasydisc do not work the current way EasyOS and Easypup are being distributed and have not worked since the switch from cdrkit to cdrtools.
You are the person that wrote the script that put many of the disk tools into this handy package called Peasydisc. It's funny that at this late stage of EasyOS/Buster development, this missing genisoimage problem is coming up? By the way, I really like this utility and use many of it's features all the time. It's simple, easy to use and it works. Thanks

Useful container sfs-downloaded Chromium-80 trick.

If you want to ready-launch in Incognito mode,
just quickly slide the container icon to the nearby edit icon
and quickly let go of the mouse.

You will see this screen;
#!/bin/sh
empty -f ec-chroot chromium

Add this more useful command to the end of the line
as this;
empty -f ec-chroot chromium --incognito
and file>save

Clicking the Chromium icon will now ready-launch
Chromium in incognito mode.
Regards.
