Because it is under / in the lvm. /boot does not have to be vfat, it is /boot/efi that has to be vfat. If you want a separate /boot for the / in the lvm you will have to create a separate partition for it during install (custom), but it is *not* required, thus why you did not get a prompt. > I have: > > [paul@localhost /]$ sudo parted /dev/sda -- print > [sudo] Mot de passe de paul : > Modèle : ATA ST500LM021-1KJ15 (scsi) > Disque /dev/sda : 500GB > Taille des secteurs (logiques/physiques) : 512B/4096B > Table de partitions : gpt > Drapeaux de disque : > > Numéro Début Fin Taille Système de fichiers Nom > Drapeaux > 1 1049kB 268MB 267MB ext4 > 2 269MB 479MB 210MB fat16 > démarrage, esp > 3 479MB 701MB 222MB fat16 EFI System > Partition démarrage, esp > 4 701MB 194GB > 193GB lvm > > [paul@localhost /]$ lsblk > NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT > sda 8:0 0 465,8G 0 disk > ├─sda1 8:1 0 255M 0 part /boot > ├─sda2 8:2 0 200M 0 part > ├─sda3 8:3 0 212M 0 part /boot/efi > └─sda4 8:4 0 180G 0 part > ├─myLVM-fedoraMain 253:0 0 80G 0 lvm / > └─myLVM-fedoraSwap 253:1 0 9G 0 lvm [SWAP] > sr0 11:0 1 6,6G 0 rom > /run/media/paul/090130_0113 [paul@localhost /]$ Fedora can't run without a / partition, usually defaults to ext4, but many other fs types available /boot, ext? usually, but I *think* can be *some* other types. Can be under /, then no separate /boot needed. /boot under the / partition the default now. Is there not a /boot under the / in the lvm partition after install? Are there not entries in /boot/loader/entries/ of the /boot in the lvm partition? /boot/efi required to be vfat by the uefi standard Is there no /boot/efi/EFI/fedora directory with entries corresponding to the lvm partition? _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
