Hi, I have got a 4.2-STABLE box, cvsup'ed the last time 3 hours ago the whole world and the ports collection. After building the world and the kernel, "make KERNEL=MYKERNEL installkernel" (in multiuser mode, but I am the one and only user at this time) fails with an "operation not permitted" error executing "chflags noschg /kernel" as root. Rebooting in single user mode, make installkernel, reboot to single user, make installworld, mergemaster works fine. After this I rebooted again (into multiuser), built the latest XFree86-4, but can't get it to work. xf86cfg fails because a fatal X server error occurs: (WW) checkDevMem: failed to open "/dev/mem" (Operation not permitted) [...] Fatal server error: xf86EnableIO: Failed to open /dev/io for extended I/O (I started xf86cfg as root) The manpages for io(4) and mem(4) didn't give me a hint what happened, the search on deja.com and freebsd-(stable|questions) was unsuccessful. Running xf86cfg or startx within truss also didn't show some helpful output. Another problem in the same category (I think): I tried to copy a file with "mcopy foo a:" (as root) and got Can't open /dev/rfd0: Operation not permitted. All 3 device files (/dev/io, /dev/mem, /dev/rfd0) are read-writable for root. Any hints appreciated.
