When playing with MSS (shared user database with glftpd) and trying to sync…
you might run into an error message like this
./mss-core.sh fullsync debug
Attempting to remount FTP_DATA_EXT ( /glftpd/ftp-data.ext ).
Verify user glftpd does not exist. Remount failed.
this is just another example of poor scripting that makes you waste a lot of time, looking at all the wrong places.
the script it self shows that its a nfs issue, and that the nfs-common package is missing.
so install it, and your good to go
