Storage, volumes & filesystems

From a block device to a mounted filesystem, without a C library anywhere.

Organisation	Repos	Site	Docs	What it holds
go-volumes	9	site	docs	The block layer — a device contract, NBD, pools, replicas, S3, an OCI image as a block device, GPT and MBR, and parse-hardening guards.
go-filesystems	20	site	docs	Filesystem-format drivers — ext4, xfs, btrfs, zfs, apfs, ntfs, exfat, fat32, iso9660, squashfs and more — plus UEFI variable management and a format prober. And the other direction: NFSv3, SFTP and WebDAV servers that export any of them, so an image can be mounted by the host rather than only read by a program.
go-diskimages	6	site	docs	Disk-image formats: qcow2, raw, dmg, tart-oci, in either direction.
go-fsctl	6	site	docs	Linux kernel ioctl wrappers — zfs, btrfs, loop, device-mapper, block, copy-on-write clones.
go-fde	4	site	docs	Full-disk encryption: LUKS, APFS, and the plumbing that opens them.
go-encryptions	3	site	docs	The modes underneath: CCM, XTS, ZFS crypto.

Counts are public repositories that hold code; brand, docs and landing repositories are excluded.
