Thanks Gary, It seems COMPAT_FREEBSD7 has more scope than [456] ( /usr/src/UPDATING I should read more often. ) But /usr/src/UPDATING is a transition log, & as new things occur, the entry re COMPAT_FREEBSD7 will get buried deeper. Requirement from COMPAT_IA32 for COMPAT_FREEBSD7 applies with amd64 but not i386, so I'd suggest that could be documented in /sys/amd64/conf/GENERIC , eg From options COMPAT_FREEBSD7 # Compatible with FreeBSD7 To options COMPAT_FREEBSD7 # Compatible with FreeBSD7, req. by COMPAT_IA32 Cheers, Julian -- Julian Stacey: BSD Unix Linux C Sys Eng Consultants Munich http://berklix.com Mail plain text, Not HTML quoted-printable Base64 http://www.asciiribbon.org
