@Schievel1 can you get a glimse ?
Sorry, but I do not understand what you mean by this. It probably is because I am using timeshift personally and just use snapper occasionally when testing out things.
ok, I read that but I am still a bit confused what you want to do.
Do you want to create a new grub submenu whenever snapper makes a new snapshot? This is actually what grub-btrfsd
is for, but you could do a script like this in /usr/lib/snapper/plugins
#!/usr/bin/env bash
create_grub_menu() {
# create the grub submenu of the whole grub menu, depending on whether the submenu already exists
# and gives feedback if it worked
if grep "snapshots-btrfs" "${GRUB_BTRFS_GRUB_DIRNAME:-/boot/grub}"/grub.cfg; then
if /etc/grub.d/41_snapshots-btrfs; then
echo "Grub submenu recreated"
else
echo "[!] Error during grub submenu creation (grub-btrfs error)"
fi
else
if ${GRUB_BTRFS_MKCONFIG:-grub-mkconfig} -o "${GRUB_BTRFS_GRUB_DIRNAME:-/boot/grub}"/grub.cfg; then
echo "Grub menu recreated"
else
echo "[!] Error during grub menu creation (grub/ grub-btrfs error)"
fi
fi
}
if [[ $1 == "create-snapshot-post" || $1 == "delete-snapshot-post" ]]; then
create_grub_menu
fi
Something like that?
@Schievel1 yes something like this snapper could be send in modern language push notification every time it create an interesting notification.
You use here a full hammer that is every time you get a notification, you recreate the whole menu, but if you could run grub-btrfs special hook it could be more efficient
Hi,
I really believe for snapper a good configuration is plugins one create-snapshot-post subvolume fstype snapshot-number delete-snapshot-post subvolume fstype snapshot-number
Could you please give me some guidance of how achieve this kind of modification ?
Thanks
