All users of bfu, read this:

On Wednesday, November 23, this putback was done to /ws/onnv-gate:

Comment:
6210677 dirname and basename are slower than they should be
Files:
update: usr/src/Makefile.lint
update: usr/src/cmd/basename/Makefile
update: usr/src/cmd/basename/basename.c
update: usr/src/cmd/dirname/Makefile
rename from: usr/src/cmd/basename/basename.sh
         to: deleted_files/usr/src/cmd/basename/basename.sh
create: usr/src/cmd/dirname/dirname.c
rename from: usr/src/cmd/dirname/dirname.sh
         to: deleted_files/usr/src/cmd/dirname/dirname.sh

This converted /usr/bin/basename and /usr/bin/dirname from
being shell scripts to being ELF executables.

This is a Good Thing, but unfortunately bfu really expects them
to be shell scripts and applies transformations to them
for its own bfu-safe environment that are appropriate only
for shell scripts, not ELF executables.

This leads to bfu errors when the system being bfu'd has already
been bfu'd once to include the above change.

I just putback a fix to bfu for this problem:

Comment:
6355592 fix for 6210677 breaks bfu
Files:
update: usr/src/tools/scripts/bfu.sh

This makes bfu behave properly for both pre- and post- updating
of /usr/bin/basename and /usr/bin/dirname

/ws/onnv-gate/public/bin/bfu will soon be updated by the gatekeepers.
If you use a bfu script from some other place, be sure to update
it as soon as possible from /ws/onnv-gate/usr/src/tools/scripts/bfu.sh
