| 2020-08-25 | Remove "guile-zlib" extension when unused....This is a follow-up of 755f365b02b42a5d1e8ef3000dadef069553a478.
As (zlib) is autoloaded in (gnu build linux-modules), "guile-zlib" is needed
as an extension only when it is effectively used.
* gnu/installer.scm (installer-program): Remove "guile-zlib" from the extensions.
* gnu/machine/ssh.scm (machine-check-initrd-modules): Ditto.
* gnu/services.scm (activation-script): Ditto.

| 2020-08-25 | linux-libre: Support module compression....This commit adds support for GZIP compression for linux-libre kernel
modules. The initrd modules are kept uncompressed as the initrd is already
compressed as a whole.
The linux-libre kernel also supports XZ compression, but as Guix does not have
any available bindings for now, and the compression time is far more
significant, GZIP seems to be a better option.
* gnu/build/linux-modules.scm (modinfo-section-contents): Use
'call-with-gzip-input-port' to read from a module file using '.gz' extension,
