I build my own kernel with ABS.
To allow my nspawn container to load kernel modules, I must add this to nspawn unit file: --capability=CAP_SYS_MODULE.
Unfortunately, it doesn't work and needed modules are not loaded from container but only from host. I realized there is no #define CAP_SYS_MODULE in /usr/lib/modules/4.1.2-2-ARCH/build/include/linux/capability.h.
Is this specific to the arch kernel ?
Thank you for hints.

Thank you for hints.
It was moved to include/uapi/linux/capability.h recentlyish.
As for your actual issue, SYS_CAP_MODULE isn't listed in the valid capabilities for --capability in the systemd-nspawn manpage. Are you perhaps confusing options?

Not at all, but you are right, it is not mentioned in systemd-nspawn man. But according to Mr Systemd, it is a valid option.

The fact it has been moved could well explain why it doesn't work for my container ?

Look at /usr/include/linux/capability.h (linux-api-headers) instead.

Not really, more like December 2012, with kernel 3.7.

Looking at the manpage it doesn't say "valid", it's just a list of default capabilities.

Much better indeed. TY
