New Revision: 247767
URL: http://svnweb.freebsd.org/changeset/base/247767
Log:
MFC r226775:
- Add support for a "!" character in regex matching in devd(8). It inverts
the logic (true/false) of the matching.
- Add "!usbus[0-9]+" to IFNET ATTACH notification handler in the default
devd.conf to prevent rc.d/netif from running when usbus[0-9]+ is attached.
