Description Ed Maste freebsd_committer freebsd_triage 2023-03-07 20:58:37 UTC 
When running `make makeman`:
no description found for WITH_LOADER_VERIEXEC_VECTX, skipping

I'm adding other descriptions in https://reviews.freebsd.org/D38961 but I'm not sure what the text should be for this option.

Comment 2 Simon J. Gerraty freebsd_committer freebsd_triage 2023-03-08 17:54:00 UTC 
Sorry about that.  The purpose of WITH_LOADER_VERIEXEC_VECTX is to enable
hashing (thus verifying) kernel and modules as a side effect of loading.
This avoids the double I/O of the simple method used for non-modules which tend to be much smaller.
