Suspected Bug in git install procedure [ git-daemon-run (version 1:2.9.3-1) ]

[Jean-Marc B. van Schendel]

Hi,

Not really a bad bug, apparently just one little detail...

Symptoms:
On a fresh new install of Debian "Stretch" (8.5 alpha7, dated 2016-06-30),
Trying to install a subset of Git packages (roughly, all those listed
in git-all, except CVS-related packages)
Install of package git-daemon-run (version 1:2.9.3-1) fails, dpkg
reporting error

Assumed cause:
The directory /etc/service does not exist, and the install procedure
does not create it, subsequently fails to create a symlink (git-daemon
--> /etc/sv/git-daemon)

Workaround used:
Manually created, directory /etc/service and ... it seems to work fine...

Dunno's...
It seems like the location for the newly created symlink may be
hard-coded as /etc/service/. I cannot substantiate whether this
location is a "universal invariant", or something platform-specific,
which ought to be documented in one way or another.
The "real'' cause of the problem might as well be that the install of
Debian silently failed to create /etc/service/ (either as a folder or
as a symlink to anwhere else)...
The git daemon is the first standalone daemon I am installing on this
system. From my point of view, it sounds possible that another
standalone daemon (eg. ProFTPd) might have reported the same problem
if I had installed it before git...


Kind regards

The git-daemon-run package is entirely a Debian creation, and has more
to do with "runit" than it does with "git daemon" itself. In particular,
your problem:

looks like it's about the system runit setup. I didn't dig, but it's
probably related to:

Thanks for the reply...
Indeed there was a problem with the runit package (2.1.2-5), which
_should_ have created /etc/system/ as a link to (in my case)
/etc/runit/runsvdir/current ...
Upgrading to runit 2.1.2-6 clears this off.
