With

nfs:/home /home nfs defaults 0 0

in /etc/fstab I get

mount.nfs: Failed to resolve server nfs: Temporary failure in name resolution

on boot. This is because I use local bind9 and /etc/resolv.conf has

nameserver 127.0.0.1

I tried adding " bind9" to the $remote_fs line of /etc/insserv.conf but got

$ sudo insserv --dryrun
insserv: There is a loop between service bind9 and rsyslog if started
insserv: loop involving service rsyslog at depth 8
insserv: loop involving service bind9 at depth 7
insserv: loop involving service mountnfs at depth 5
insserv: loop involving service atd at depth 11
insserv: exiting now without changing boot order!

Any idea on how to proceed? I'd hate to use numeric IP addresses.

Mmm, as per "man insserv" page, better try to force the availability of
bind9 by:

/etc/insserv.conf

***
$named bind9
***

(remove the "+" which means the service is optional)

And restore the original "$remote_fs" line...

So we are doing something wrong here.

Did you read the manual or the docs for insserv? Maybe we are missing some
step to fully populate the new boot sequence :-?

(side note: Apache is also giving you a warning)

Still getting NFS service before bind9. Looks like changes are not applied
(or ignored).

Check the scripts (nfs and bind9) headers.

I did try but the man page does not really mention when symlinks are
created. For example

$ echo /etc/rc*/*bind9
/etc/rc0.d/K02bind9 /etc/rc1.d/K02bind9 /etc/rc2.d/S19bind9 /etc/rc3.d/S19bind9 /etc/rc4.d/S19bind9 /etc/rc5.d/S19bind9 /etc/rc6.d/K02bind9
$ sudo rm /etc/rc*/*bind9
$ sudo insserv
$ echo /etc/rc*/*bind9
/etc/rc*/*bind9

does not seem to recreate them but

$ sudo update-rc.d bind9 enable
update-rc.d: using dependency based boot sequencing
update-rc.d: error: no runlevel symlinks to modify, aborting!
$ sudo ln -s ../init.d/bind9 /etc/rc2.d/S20bind9
$ sudo update-rc.d bind9 enable
update-rc.d: using dependency based boot sequencing
insserv: warning: current start runlevel(s) (2) of script `bind9' overwrites defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (empty) of script `bind9' overwrites defaults (0 1 6).
$ echo /etc/rc*/*bind9
/etc/rc2.d/S19bind9

does (and note how S20 was turned into S19). A way to "regenerate"
symlinks for all runlevels thus becomes

$ sudo update-rc.d -f bind9 remove
update-rc.d: using dependency based boot sequencing
$ sudo update-rc.d bind9 defaults
update-rc.d: using dependency based boot sequencing
$ echo /etc/rc*/*bind9
/etc/rc0.d/K02bind9 /etc/rc1.d/K02bind9 /etc/rc2.d/S19bind9 /etc/rc3.d/S19bind9 /etc/rc4.d/S19bind9 /etc/rc5.d/S19bind9 /etc/rc6.d/K02bind9

If instead of changing "+bind9" to "bind9" in /etc/insserv.conf I
change

# Required-Start: $remote_fs
# Required-Stop: $remote_fs
# Should-Start: $network $syslog
# Should-Stop: $network $syslog

to

# Required-Start: $local_fs
# Required-Stop: $remote_fs
# Should-Start: $network
# Should-Stop: $network $syslog

in /etc/init.d/bind9 then I do get desired ordering in runlevel 0:

$ echo /etc/rc*/*bind9
/etc/rc0.d/K02bind9 /etc/rc1.d/K02bind9 /etc/rc2.d/S01bind9 /etc/rc3.d/S01bind9 /etc/rc4.d/S01bind9 /etc/rc5.d/S01bind9 /etc/rc6.d/K02bind9
$ echo /etc/rc*/*mountnfs.sh
/etc/rc0.d/K05umountnfs.sh /etc/rc6.d/K05umountnfs.sh /etc/rcS.d/S16mountnfs.sh

This, however, does not help since mountnfs.sh is run already in
runlevel S. As an exercise I added bind9 to Required-Start of
/etc/init.d/mountnfs.sh

$ sudo update-rc.d -f mountnfs.sh remove
update-rc.d: using dependency based boot sequencing
$ sudo update-rc.d mountnfs.sh defaults
update-rc.d: using dependency based boot sequencing
update-rc.d: warning: mountnfs.sh start runlevel arguments (2 3 4 5) do not match LSB Default-Start values (S)
update-rc.d: warning: mountnfs.sh stop runlevel arguments (0 1 6) do not match LSB Default-Stop values (none)
$ echo /etc/rc*/*mountnfs.sh
/etc/rc0.d/K05umountnfs.sh /etc/rc6.d/K05umountnfs.sh /etc/rcS.d/S16mountnfs.sh

but mountnfs still gets started in S runlevel and thus before
bind9. Next, I changed Default-Start of /etc/init.d/mountnfs.sh from
"S" to "2" and finally bind9 seems to start before mountnfs.sh:

$ echo /etc/rc*/*mountnfs.sh
/etc/rc0.d/K05umountnfs.sh /etc/rc2.d/S16mountnfs.sh /etc/rc6.d/K05umountnfs.sh
$ echo /etc/rc*/*bind9
