The problem is that for monolithic kernels the filesystem code lies in
kernelspace, hence for security reasons filesystems can only be attached
(via mount) by root. (This isn't applicable to the GNU system, though,
since Hurd's ext2fs is implemented as a userspace server that normal users
can run)

With this utils, normal users still can't use standard filesystem C library
calls over their custom ext2fs image, but may use commands like e2cp or
e2mkdir for basic manipulation.

Btw, I need this to integrate grub-disk into the grub package (see #190392).
