Package: debian-policy
Version: 3.8.2.0
Severity: normal
Hello policy makers :)
update-inetd is seriously bug infested, IMHO to some extent because of the
issue below.
Policy 11.2 says:
If a package wants to install an example entry into `/etc/inetd.conf', the
entry must be preceded with exactly one hash character (`#'). Such lines
are treated as "commented out by user" by the `update-inetd' script and
are not changed or activated during package updates.
[presumably, "not changed" here implies also "not deleted"]
Effectively this means that we cannot distinguish between two entirely
different things: local-admin-policy and examples generated by postinst
maintainer scripts.
Now how does this lead to bugs? Say I install ftp-daemon-a, which adds an
example entry to /etc/inetd.conf, and then I uninstall the package. The
example entry will survive the package's removal (even if prerm calls
update-inetd, it won't be removed because it's indistinguishable from
local-admin-policy).
Then I decide to install ftp-daemon-b. If the package's postinst calls
update-inetd to enable the new service, the new entry won't be added because
it's apparently local-admin-policy that ftp should be disabled.
A potential fix would be to prescribe that example entries added by maintainer
scripts are preceded with '#<example># ' (to be consistent with '#<off># '
which is what update-inetd uses by default to denote disabled entries).
Cheers,
Serafeim
