No, it starts with the bash shebang:

#!/bin/bash

It's soooo full of bashisms I wouldn't know where to start.  The substitution 
line with the error is shown below, but my regex-fu is not good enough to 
troubleshoot it:

# browser is on system so check profiles
#
# check that the LAST DIRECTORY in the full path is unique
  unique_count=$(echo ${DIRArr[@]##*/} | sed 's/ /\n/g' | sort | uniq | wc -l)
     if [[ ${#DIRArr[@]##*/} -eq $unique_count ]]; then
     return # no problems so do nothing
     else
     echo -e " ${RED}Error: ${NRM}${BLD}dup profile for ${GRN}$browser${NRM}$
{BLD} detected. See psd manpage, correct, and try again."${NRM}


I also noticed the startup script has not yet been converted to openrc-run:

# /etc/init.d/psd restart                                              
 * /etc/init.d/psd uses runscript, please convert to openrc-run.                 
 * Starting Profile-Sync-Daemon ...                                              
/usr/bin/profile-sync-daemon: line 325: ${#DIRArr[@]##*/}: bad substitution [ 
ok ]
