As we tried, fscaps is 1 also in the obs-build kernel (it cannot be different
as it is repackaged kernel-default package).

Looking at the output:
[   16s] util-linux-2.37.2-2.3                
########################################
[   16s] Warning: running kernel does not support fscaps
[   16s] /usr/bin/mount: setting to root:root 4755 (wrong permissions 0755)

Clearly it warns even before mount(1) is installed. So /sys/ is definitely not
instantiated at that phase.
