Hello,
To update a system installed on a specific partition that way? (after dnf update --refresh) mount /dev/sdx /mnt/linux chroot /mnt/linux dnf system-upgrade download --releasever=40
Thanks

I wouldn't trust it. I'll often use chroot to download updates, but to actually run them there are too many things I imagine need a "real" system to apply the updates. All the stuff from /proc and /sys that some updates might need aren't going to be there in a chroot for one example.
you need to add these mounts to allow full function under a rescue boot+mnt+chroot.
mount -o bind /proc /mnt/linux/proc mount -o bind /sys /mnt/linux/sys mount -o bind /dev /mnt/linux/dev mount -o bind /dev/pts /mnt/linux/dev/pts
Typed from memory. I have done way too many live cd rescue boots.

dnf has "--installroot=<path>". Requires absolute path. No idea if it works with system-upgrade.
Hi.

I don't see this option in its man page, but since the goal if not to upgrade the current system, but a system in a separate partition, using system-upgrade is not needed. A simple:
dnf --installroot /mnt/linux --releasever=40 distro-sync
is sufficient, but after, as Roger said, having mounted /proc /sys ... under /mnt/linux.
I usually only bind mount:
dev proc run sys tmp
to properly use a system in a separate partition with chroot.
The whole actions would thus be:
for i in dev proc run sys tmp; do mount --bind /$i /mnt/linux/$i;done dnf --installroot /mnt/linux --releasever=40 distro-sync

I found the option in the dnf man page - not sure why you don't see it?

Sorry, I was unclear: I talked of the man page of dnf-system-upgrade.

Beware, you may also have to mount some other partitions as for example /mnt/linux/boot or /mnt/linux/boot/efi.
Check /mnt/linux/etc/fstab.
Currently I am hesitating to do chroot
The point is the following running grub2-mkconfig I get Found Fedora Linux 38 (Thirty Eight) on /dev/sdc4
but efibootmgr does not the distribution and grub2 does not show it In addition at boot EFI does not offer me the option to boot to this sdc4 partition

Should I run grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg and not grub2-mkconfig -o /boot/grub2/grub.cfg. ?

No: since a few fedora versions, /boot/efi/EFI/fedora/grub.cfg simply redirect to /boot/grub2/grub.cfg.
Can you describe what disk/partitions you have ?
I guess you have two disks, each with a system and an EFI partition

This I do not understand On the installation which provides troubles (I can only boot through super grub) I have /dev/sdc3 23800324 15253780 7313160 68% / /dev/sdc2 432924 282442 123500 70% /boot
os-prober does not see /dev/sdc3 but in /boot/grub2/grub.cfg I have see set root='hd2,msdos3' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd2,msdos3 --hint-efi=hd2,msdos3 --hint-baremetal=ahci2,msdos3 da1fb213-c138-4711-aba2-76a598506283
which is the installation on sdc3 There is no /boot/efi/EFI/fedora/grub.cfg If I umount /boot and mount /dev/sda3 /boot/efi (sda3 is recognized as a EFI System Partition) sdc3 does not show up in /boot/efi/EFI/fedora/grub.cfg
This seems to indicate that I need to make
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
grub-customize does not show my fedora 40 installed on sdc3 either

A bunch of other stuff will likely need to be mounted.
Pretty much anything needs /dev, /sys, etc… that needs to be mounted in your chroot.
