>Description:
In the diskless.8 man page there is an example that contradicts the text:
an NFS server which exports a root and /usr partition with appropri-
ate permissions. The rc.diskless{1,2} scripts work with readonly
partitions, as long as root is exported with -maproot=0 so that some
system files can be accessed. As an example, /etc/exports can con-
tain the following lines:
<ROOT> -maproot=0 -alldirs <list of diskless clients>
/usr -alldirs <list of diskless clients>
you see? It says to export the partitions readonly, but the example
exports them read-write! The manpage is the same on stable and current.
>How-To-Repeat:
man diskless
>Fix:
Following patch fixes this. Checked with the various docs in
/usr/share/examples/diskless/
