The NFS sources don't get mounted directly by init (in which case that line

mail.
ah, i understand now, thanks for the explanation.
That script belongs to "initscripts" (which, if my understanding is
correct, would be very dangerous to "backport" once patched) and has a
hardcoded check for /etc/init.d/portmap, so it has no knowledge of either
insserv.conf nor rpcbind.
right. the difference seems to be:

This appears to come from #620788 (cc'ed here), which i've just
unarchived in the BTS.
I'm not really an expert on these matters, but since rpcbind can
effectively replace portmap, it could be a solution to declare it as a
portmap replacement in debian/control and make it provide the rpcbind ->
portmap symlink on /etc/init.d to make things work.
It's not very clean but would allow not to touch the distribution's files
too much.
ugh, this sounds pretty painful to me, and probably not really
appropriate for squeeze-backports or debian stable.
Another solution could be to package the patched file and distribute a
patched version of initscripts in the backports, but i don't know how hard
to maintain that would be.
This approach (using the patch above) actually seems plausible to me as
something that we might want to fix in a squeeze point release, since i
think rpcbind should be a viable alternative to portmap in stable anyway.
sysvinit maintainers, release team -- what do y'all think of this
proposal? I'd be happy to prepare a package with this targeted fix for
squeeze-proposed-updates if you think that would be acceptable.
Please let me know!
