Seems ok to me.
I also proposed a patch to move %control-groups from %base-file-systems
to %elogind-file-systems.
WDYT ?
Thanks,
Mathieu

Subject: [PATCH 1/2] file-systems: Do not mount hugetlb cgroup filesystem.
On ARM32 without LPAE support, hugetlb control group is not supported.
As it is not needed by elogind, remove it for all platforms.
* gnu/system/file-systems.scm (%control-groups): Remove hugetlb from control
groups platforms.
