Hi Guix,

The following patch series adds support for Linux native filesystem encryption
to Guix, via the `fscrypt` kernel interface and associated userspace tools
`fscrypt` and `fscryptctl`.

Patch 1/4 enables the relevant kernel configuration option,
CONFIG_FS_ENCRYPTION. This is the same patch as #77202 [1].
Patch 2/4 and 3/4 add the high-level `fscrypt` command-line utility (which is
implemented in Go); these are the same patches as #77174 [2].
Patch 4/4 adds `fscryptctl`, a lower-level tool written in C; this is the same
patch as #77175 [3].

I thought it would be good to group all these patches in a single series, so
I'll close #77202, #77174 and #77175 in favor of this one.

Sounds good! I pushed the patches as
