Hi, I've noticed that the edk2 ext4 driver does case-insensitive filename matching. I know the fat filesystem is case-insensitive, and the uefi spec describing the fat filesystem also explicitly says it is case-insensitive. On a quick scan I can't find anything in the uefi spec requiring *all* filesystem drivers being case-insensitive though.
So I'm wondering whenever the ext4 driver behavior is correct. It certainly is different than the linux kernel's behavior which is (by default) case-sensitive. Also note that the linux kernel ext4 driver recently got support for case-insensitive file names, which must be explicitly enabled for both filesystems (EXT4_FEATURE_INCOMPAT_CASEFOLD) and directories (EXT4_CASEFOLD_FL). On practical terms I've ran into actual problems due to Fedora mounting the ESP at /boot/efi[1] and UKIs (unified kernel images) should be placed in EFI/Linux on either ESP or XBOOTLDR partition, which on fedora translates to /boot/efi/EFI/Linux (ESP) or /boot/EFI/Linux (XBOOTLDR). So I have both /boot/efi and /boot/EFI ... take care, Gerd [1] Yes, a bad choice for a number of reasons, but changing that isn't easy as this is hard-coded in a unknown number of places :( -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
