Well, I can only report a problem with NFS + Unionfs on 5.3. It is very easily reproduceable, though it's definitely not a minimal test or a regression test. Steps needed: # mount -t unionfs /vol /usr/ports # mount -t nfs coyote:/usr/ports on /usr/ports (nfs, read-only) # mount -t unionfs <above>:/vol on /usr/ports (unionfs, noclusterw) # cd /usr/ports/emulators/linux_base-8 # make WRKDIRPREFIX="" install ... brandelf: error opening file /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/sbin/ldconfig: Text file busy *** Error code 1 Stop in /usr/ports/emulators/linux_base-8. # brandelf -t Linux /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/sbin/* brandelf: error opening file /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/sbin/install-info: Text file busy brandelf: error opening file /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/sbin/ldconfig: Text file busy # brandelf -t Linux /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/bin/* brandelf: error opening file /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/bin/bash: Text file busy brandelf: error opening file /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/bin/bash2: Text file busy brandelf: error opening file /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/bin/chown: Text file busy brandelf: file '/usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/bin/egrep' is not ELF format brandelf: file '/usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/bin/fgrep' is not ELF format brandelf: error opening file /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/bin/grep: Text file busy brandelf: error opening file /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/bin/mv: Text file busy brandelf: error opening file /usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/bin/sh: Text file busy # brandelf -t Linux /vol/emulators/linux_base-8/work/linux_base-8-8.0/bin/* brandelf: file '/vol/emulators/linux_base-8/work/linux_base-8-8.0/bin/egrep' is not ELF format brandelf: file '/vol/emulators/linux_base-8/work/linux_base-8-8.0/bin/fgrep' is not ELF format So, trying to brandelf the files in the upper layer will fail on some files (deterministically) and brandelfing the same files in the lower layer succeeds (egrep and fgrep are false positives). I have no clue what's wrong here, and if this is already fixed in 6.0 or P4, even better! Just wanted to share a scenario where unionfs fails on 5.3.
