[Monotone-debian] Bug#483155: monotone-server: incomplete /usr/share/doc rearrangement breaks postinst

[Aaron M. Ucko]

Package: monotone-server
Version: 0.40-3
Severity: serious
Justification: Policy 12.3

Upgrading monotone-server from 0.39-1 to 0.40-3 fails because dpkg
does NOT automatically replace directories with symlinks (or vice
versa), causing the postinst's usage of ucf to error out:

Setting up monotone-server (0.40-3) ...
Error: The new file /usr/share/doc/monotone-server/examples/write-permissions 
does not exist!
dpkg: error processing monotone-server (--configure):
 subprocess post-installation script returned error exit status 1

Please add postinst logic to ensure that
/usr/share/doc/monotone-server is in fact a symlink (likewise for
monotone-doc); debconf-utils's postinst illustrates the relevant
technique.

Incidentally, as Policy 12.3 also observes, you shouldn't store
baseline configuration files (or anything else on whose presence you
rely) under /usr/share/doc anyway; please move them elsewhere (perhaps
a new /usr/share/monotone directory or even hierarchy?)

Thanks!
