Notes to myself and Googlers on instal­ling a vir­tu­al hosting con­trol panel Vir­tu­al­min (a gre­at add-on to Webmin) on Ubun­tu server:

• wget http://software.virtualmin.com/gpl/scripts/install.sh
chmod 755 install.sh
./install.sh
 — installs Vir­tu­al­min auto­ma­ti­cal­ly with all depen­den­cies, with a nice skin which is also used by Webmin (which I remem­ber used to be quite ugly by default) 
• chmod 711 /var/spool/postfix/var/run/saslauthd  — fixes login failu­re when try­ing to send mail thro­ugh vir­tu­al server
• it seems apa­che vhost, ftp, e‑mail and DNS is pro­per­ly con­fi­gu­red auto­ma­ti­cal­ly, will add more info here as I move on with my hosting migra­tion to Vir­tu­al­min probably
