[gentoo-user] merge-usr and SPF implementations

[Stefan Schmiedl]

Greetings.

After updating profiles, I decided to try switching to merged-user, too,
following the wiki page at https://wiki.gentoo.org/wiki/Merge-usr

One server reported during the dry run:
ERROR: Conflict for file '/usr/sbin/spfd': [Errno 17] File exists:
'/usr/bin/spfd'

# equery belongs /usr/bin/spfd
* Searching for /usr/bin/spfd ...
mail-filter/libspf2-1.2.11 (/usr/bin/spfd)
# equery belongs /usr/sbin/spfd
* Searching for /usr/sbin/spfd ...
dev-perl/Mail-SPF-2.9.0-r3 (/usr/sbin/spfd)

That does put me in a bit of a pickle, as both are active dependencies
pulled in by essential software:

# emerge -cav Mail-SPF

Calculating dependencies ... done!
dev-perl/Mail-SPF-2.9.0-r3 pulled in by:
mail-filter/spamassassin-4.0.0-r4 requires dev-perl/Mail-SPF

No packages selected for removal by depclean

# emerge -cav libspf2

Calculating dependencies... done!
mail-filter/libspf2-1.2.11 pulled in by:
mail-filter/opendmarc-1.4.1.1-r5 requires mail-filter/libspf2
mail-mta/exim-4.97.1-r5 requires >=mail-filter/libspf2-1.2.5-r1


What is the recommended way to proceed in this scenario?

Regards,
Stefan

My guess and this is only a guess, is the two binaries are in separate
subdirectories of /usr and therefore there shouldn't be a problem. Before you
progress with this you could raise a bug, or try to seek a dev's advice on
IRC. A fresh backup before you make any changes is definitely a good idea.

Quoting the wiki page:
"In addition, the script applies the "sbin merge" at the same time where /sbin and /usr/sbin are both actually merged to /usr/bin."
So while it is not a problem with split-usr, those two packages will clash with merged-usr.

You're right, they will be in the same subdirectory!

Thanks,

The bug report should hopefully resolve these.
