When new file is created and modified on unionfs, a part of the file is filled by zero. The size of zero-filled part is always multiple of 4096 bytes. Easy way to reproduce the problem is: # mount -t union /foo /usr/obj # cd /usr/src # make world When you got signal 11 or other error, please see /usr/obj/usr/src/tmp/usr/bin/make and /usr/obj/usr/src/usr.bin/make/.depend. One of them contains zero- filled field. Do you have any idea to solve it? ---- KATO Takenori Dept. Earth Planet.
