Have a look at http://www.goop.org/~jeremy/autofs. I've done some patches
which allows a /net-style directory to mount all filesystems being exported
from a machine. Well, that's the simple case - all the decision-making is done
in a shell-script, so you can easily tailor it to your needs.
For example, I have /etc/auto.net as a shell script:
---
#!/bin/sh
# Look at what a host is exporting to determine what we can mount.
# This is wildly simplistic - no attempt is made to see whether we can mount
# each filesystem, or whether its RO or RW. For the future...
key="$1"
opts="-fstype=nfs,hard,intr,nodev,nosuid"
showmount --no-headers -e "$key" | sort | \
sed -e "s|^\([^ ]*\).*|$key\1 $opts $key:\1|"
---
If you want, you can filter the output of showmount, put in a table-lookup,
or anything else. The script just needs to output one or more lines of the
form:
local-dir -fstype=type,options remote:/filesystem
ixodes/ -fstype=nfs,hard,intr,nodev,nosuid ixodes:/
