Re: [vserver] Oddity with df

Hi Herbert,

Agreed. I shutdown the guest and then ran a simple script which cat /vservers/guest/etc/mtab into another file. I then started the guest and checked the log file for hdv1 and saw:

/dev/hdv1 / ufs defaults 0 0
none /proc proc defaults 0 0
none /tmp tmpfs size=128m,mode=1777,nosuid,nodev,noexec 0 0
none /dev/pts devpts gid=5,mode=620 0 0

then I bit further down it changed too:

none / none rw 0 0

Oh this is going to be a real pain to track down as I do not see anything in /etc/init.d or the upstart configuration files :(

Thanks, Phil
