I added my comments to https://bugzilla.redhat.com/show_bug.cgi?id=1600778 Many subsequent attempts to use grub2-mkconfig failed to add extra options. The grub.cfg and associated files successfully boot F30. During investigation of this I found the following that may be useful. I do not understand the significance! When grub2-mkconfig is run os-prober seems to create entries of the form [root@naxos:/boot/efi/EFI/fedora]$ dmsetup ls osprober-linux-nvme0n1p7 (253:2) These entries seem to stop the mounting of the partitions [root@naxos:~]$ blkid -c /dev/null shows them as /dev/mapper/osprober-linux-nvme0n1p7: LABEL="naxos7_F29" UUID="1a9ccef1-af1c-4c26-8e4d-64a25bc56fcc" TYPE="ext4" These entries can be "removed" and hence the partition "mounted" by using dmsetup remove /dev/mapper/osprober-linux-nvme0n1p7 _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
