I am still running into this occasionally on amd64 with 13.0-STABLE,
especially while updating from src and obj directories exported over
NFS, but it happens sometimes also for locally mounted src and obj.


===> stand/i386/mbr (install)
install   -o root -g wheel -m 444   mbr /boot/mbr
===> stand/i386/pmbr (install)
install   -o root -g wheel -m 444   pmbr /boot/pmbr
===> stand/i386/boot0 (install)
install   -o root -g wheel -m 444   boot0 /boot/boot0
===> stand/i386/boot0sio (install)
install   -o root -g wheel -m 444   boot0 /boot/boot0sio
===> stand/i386/boot2 (install)
objcopy -S -O binary boot2.out boot2.bin
objcopy: open boot2.bin failed: Read-only file system
*** Error code 1

Running make buildworld with only one job solves the issue. I am
building with WITH_META_MODE=yes, so I work around this by subsequent
builds:
make -sj32 buildworld && make -s buildworld
