I scoured the docs, restore from desktop was removed with 7.4 with some comments about following the prompts during install, but I didn't see any ! I looked at a Red Hat posting for the tar info.
Good news is, the following SME script worked when I retried it after some reboots and other attempts
From SME docs, note that I was using SME 7.4 and MySQL 4.1.22
Restoring accidently deleted MySQL root user
Note: The following is only applicable on SME 7.3 and MySQL 4.1
cd /var/service/mysqld
sv d .
echo 'use mysql;'>set.rootuser
echo -n 'INSERT INTO user VALUES("localhost","root","",'>>set.rootuser
echo '"Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","Y","","","","",0,0,0);'>>set.rootuser
expand-template /root/.my.cnf
expand-template /var/service/mysqld/set.password
/usr/libexec/mysqld --bootstrap --user=mysql --skip-grant-tables < set.rootuser
/usr/libexec/mysqld --bootstrap --user=mysql --skip-grant-tables < set.password
Thanks for the reply Charlie, it got me searching again & I decided to retry the script after a clean boot.
