So I just wrapped my head around vfs(9) with regard to making ktrace following symlinks again, however I don't quite understand what problems may occur when doing so. May anyone enlighten me on this?
This feature was explicitly disabled 17 years ago[1] appearently because FreeBSD did so[2] but I couldn't find any further explanation. 1: http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/kern/kern_ktrace.c.diff?r1=1.19&r2=1.20 2: https://svnweb.freebsd.org/base?diff_format=u&view=revision&revision=50668
