I'm using Webmin 1.580 with Ubuntu 12.04 and created an NFS export (export/media) which works perfectly fine after manually enabling the export, but when I reboot the system it tells me that it is unable to mount it, and I need to skip it in order to resume booting. How can I find out the root cause of this problem?
I've already seen that, it seems to be a common issue these days. I'm also almost sure I've already solved the same problem on one of my machines, but unfortunately I don't remember how. What I remember is that was a dependency problem (NFS mountpoints mounted before the network was up). Try this solution https://bbs.archlinux.org/viewtopic.php?id=118251 and good luck.
