A lot has changed since 2018 when exFAT was kept out of Fedora due to patent issues and a third-party FUSE-driver needed to be used. Until recently the GPLv2 based driver from Microsoft wasn’t enabled in the kernel as it was based on an older specification and wasn’t fully functional for everyday use.
$ grep EXFAT /boot/config-`uname -r` # CONFIG_EXFAT_FS is not set
Fedora 32 recently received an upgrade to kernel 5.7 and with that, the native exFAT driver was enabled during compile time. The driver got a lot of updates from Samsung to work correctly to the latest specifications.
# DOS/FAT/EXFAT/NT Filesystems CONFIG_EXFAT_FS=m CONFIG_EXFAT_DEFAULT_IOCHARSET="utf8" # end of DOS/FAT/EXFAT/NT Filesystems
When an SD-card is now plugged into the machine, the kernel module is loaded and the filesystem is mounted by the kernel without the need of a userland driver.
$ lsmod | grep fat exfat 81920 1 vfat 20480 1 fat 81920 1 vfat $ mount | grep fat /dev/nvme0n1p1 on /boot/efi type vfat (rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=ascii,shortname=winnt,errors=remount-ro) /dev/mmcblk0p1 on /run/media/user/disk type exfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,iocharset=utf8,errors=remount-ro,uhelper=udisks2)
The userland tools may come with Fedora 33, but the package exfat-utils from RPMFusion still need to be installed until it ships with Fedora.
