Hi Guix,
Mounting %control-groups fails on ARM32 platform because we build a
kernel without LPAE support which implies hugetlb control group cannot
be supported.
Like Debian we could have an ARMMP and ARMMP-LPAE kernel but the problem
would still exists for ARMMP.
I'm not sure what do about, a workaround could be the ugly hack
attached, WDYT ?
Thanks,
Mathieu
