Re: [gentoo-user] NFS mounting

[Matt Jolly]

It should not matter; the virtual root involves bind mounting directories into a single location - that could be 4 different partitions, a bunch of subvolumes, or some directories scattered across a single partition, or some combination of those options.

Cheers,

Matt

If you are referring to the NFS-utils wiki page:

https://wiki.gentoo.org/wiki/Nfs-utils

it provides an example of exporting two *different* partitions:

Device       Mount directory     Description
/dev/sdb1    /home               Filesystem containing user home directories.
/dev/sdc1    /data               Filesystem containing user data.
