I'd say this is a HUGE inconvenience, if I had to categorize it. I just found out the painful way that, for some odd reason, named and httpd are not set to auto-start upon reboot. This is on a Centos 4.2 server, with a virgin installation of virtualmin, updated to latest version.
Had to take the server down a while ago to swap some hardware, and upon rebooting, neither DNS/named, nor web server/httpd were running... Granted, quick fix by turning it on manually, and setting ntsysv to auto-start these services, but shouldn't a virtualmin server have these set to auto-start, you know?
Odd, but if this is indeed an versight, it should be fixed immediately.
