This looks like a bug to me. In /usr/lib/brand/shared/common.ksh,
install_dir() is responsible for the "cd && find | cpio" that you see
logged above.
722 list=$(cd "$source_dir" && ls -d * | egrep -v "$filt")
723 flist=$(for i in $list
724 do
725 printf "%s " "$i"
726 done)
727 findopts="-xdev ( -type d -o -type f -o -type l ) -print"
728
729 vlog "cd \"$source_dir\" && find $flist $findopts | "
730 vlog "cpio $cpioopts \"$ZONEROOT\""
731
732 # Ignore errors from cpio since we expect some errors depending on
733 # how the archive was made.
734 ( cd "$source_dir" && find $flist $findopts | \
735 cpio $cpioopts "$ZONEROOT" )
736
The list ($list) generated on line 722 will not include dot files. It
should probably look like:
list=$(cd "$source_dir" && ls -A | egrep -v "$filt")
Notice that "ls -d *" changed to "ls -A". I've opened:
7099779 zoneadm attach -d loses dot files in root directory
