[PKG-OpenRC-Debian] Bug#874790: /lib/rc/bin/lsb2rcconf: Boot dependency does not work for nfs-common

[Palo M.]

Package: openrc
Version: 0.23-1+b1
Severity: normal
File: /lib/rc/bin/lsb2rcconf

Dear Maintainer,

After switching to openrc, the daemons of package nfs-common (statd, idmapd,
gssd) do not start, because they depend on rpcbind (which is not started by
openrc before nfs-common).

When looking into source of lsb2rcconf I have found that it reads only file
/etc/insserv.conf to solve dependencies of legacy rc scripts.
However, the package rpcbind (which provides portmap service) installs its
info into /etc/insserv.conf.d/rpcbind (and with sysv-rc also files in
/etc/insserv.conf.d/ are read together with /etc/insserv.conf so it starts
as intended when sysv-rc is used).
So most likely lsb2rcconf should also read the files in /etc/insserv.conf.d/
to be able to solve all the dependencies. (Some other packages add their
files into /etc/insserv.conf.d/ too, for example dnsmasq or maradns.)

I tried the small workaround: I added content of /etc/insserv.conf.d/rpcbind
to the end of /etc/insserv.conf. Afterwards the rpcbind is indeed started
before nfs-common and all works fine.

Attached below are the files default_rc.log and default_checks.txt showing
the situation in default case (without workaround).
The files workaround_rc.log and workaround_checks.txt below show the
situation after workaround is applied.


Kind regards,
Palo M.
