[gentoo-user] mtab inside chroot

[Zhu Sha Zang]

Hi there, i've installed a debian/zimbra inside a chroot envorment using
gentoo. But, the command df -h don't work cos i don't have /etc/mtab
arch in chroot. How i can sync/create, or make df -h work correctly.

For now, i gain this message:

*/bin/df: cannot read table of mounted file systems: No such file or
directory*


Another question, what the difference between this packages:

*app-emulation/virtualbox-bin*
*
app-emulation/virtualbox-ose*


Thanks for now.
