NOBLE 24.04 Persistence is not enabled

[geole0]

I'm trying to make persistence work in an installation boot without success.

I suspect that the "persistence" parameter which is no longer recognized may be the cause.
However, it is possible that with this version there is a new technique to enable persistence. But I can't find how to do it.
Thank you for your reply

Your report shows you booted with 'persistent' as the parameter, which is correct and is still supported. Why do you claim that it is "no longer recognized"?

This seems reasonable.

What media are you booting from, how did you prepare it? Persistence only works if the boot medium is writable and has room for the addition of a persistence partition.

Good morning
I was worried because I read

 Unknown kernel command line parameters "persistent splash BOOT_IMAGE=/casper/vmlinuz", will be passed to user space.

My live USB is like that

a@b:~$ lsblk -fe7 /dev/sdd
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
sdd
├─sdd1 vfat FAT32 USBUNET 72EE-4CCC 219,9M 96% /media/a/USBUNET
├─sdd2 ext4 1.0 casper-rw 06f20fd7-c411-4aa5-be02-7b11934f71b9 7,1G 4% /media/a/casper-rw
└─sdd3 exfat 1.0 USBEXFAT F6BD-F745 660,9M 0% /media/a/USBEXFAT
a@b:~$

I don't know if this partition should mount automatically or if it's up to me to mount it. If yes, how?

The DF command did not list this partition as mounted.

THANKS

Good morning.
During the first try, I made a mistake in using it.
I just started again under the same conditions and persistence works well.
With my regrets.
