Hello,
I would like to mount (read-write) the ventoy partition from a live linux distribution that booted from ventoy. I tried 2 different versions but I have the same problem.
I type as root :
# mount -t auto -o rw /dev/sdb1 /mnt/newlycreatedmountpoint
It does not work. The message is : already mounted or mount point busy
The partition is not already mounted, of course, and the mount point has been created manually and is not busy.

Currently you can't mount /dev/sdb1 rw. Because a device mapper is created based on the ISO files in sdb1, and this will make /dev/sdb1 readonly and busy.
If you just want to write or save something into the USB you can wait for the next release.
In the next release, you can reserve some disk space when installing Ventoy. After that you can make /dev/sdb3 /dev/sdb4 with the reserved space and you can mount them as you want in the live system.

Thank you for your answer.
I have tried to resize the Ventoy partition, and create a new one; and it worked. It is not as flexible as to put everything in the same partition.

Hello
You said "Currently you can't mount /dev/sdb1 rw. Because a device mapper is created based on the ISO files in sdb1, and this will make /dev/sdb1 readonly and busy."
Would I be stupid to say that it is abnormal to forbid me to write in a partition for the only reason that software has reserved two files for itself. Shouldn't there be a mount option like yes-i-know-that-i-am-doing ?
The idea would then be to open a software bug with the manufacturer
In principle, I would only be interested in mounting a read / write directory in bind technique!
Thinks.

In the future release, I will provide an option for read-only or rw.
If choose read-only (default is read-only), device-mapper will be used in the backend.
If you really need to write something into the partition 1 during install OS. you can choose rw, then fuse will be used in the backend.
Device-mapper performs much better than fuse.
Besides, if you use exFAT or NTFS for partition 1, you must confirm that the disto you use can mount this partition.

Hello
I'm glad to know that in the future I could access the ISO partition in writing.
I plan a public directory and a private directory which will be protected by veracryt
I will no longer use the third partition !!!!
Thanks..
