NFS setup

In /etc/exports file, add the following lines:

/var/lib/pulse2/imaging/computers *(async,rw,no_root_squash,subtree_check)
/var/lib/pulse2/imaging/masters *(async,rw,no_root_squash,subtree_check)
/var/lib/pulse2/imaging/postinst *(async,ro,no_root_squash,subtree_check)

Then reload the new NFS configuration, as root.

Check the export list:

# showmount -e
