Not sure why the snark but if people are running FreeBSD then they should be...basket weaving instead of using it? Yes, the correct solution is to patch and reboot but not everyone is in a place to jump and do that which is why a temp workaround, if possible, would be welcome
There was no snark. If you have something of importance running and the inevitable discovery of an LPE is something you don’t have defense for or can quickly mitigate you’re doing a bad job as a sysadmin.
For all general purpose OS in common use today that usually means patch and reboot should be an NBD workaround.
