lib/libc/sys/cap_enter.2
75–76 ↗	(On Diff #20669)	is it sufficient to remove ", then for any process executing in a capability mode sandbox, "? After all, these errors only occur there. It simplifies the sentence but is maybe less clear if readers are unfamiliar with ENOTCAPABLE/ECAPMODE.

lib/libc/sys/cap_enter.2

lib/libc/sys/cap_enter.2
75–76 ↗	(On Diff #20669)	What's more, [ENOTCAPABLE] may occur outside of capability mode, since capability rights are always respected. This might be useful when passing a file descriptor to a process with a lower privilege level. In this case, no SIGTRAP occurs.
