Package: iproute2
Severity: important
Version: 6.1.0-2
X-Debbugs-CC: bluca@debian.org formorer@debian.org

Dear Debian iproute2 maintainers,

When upgraded from Debian 11 to Debian Testing/Sid (Debian 12), typing "ip mo"
no longer matches with "ip monitor". Instead, it matches "ip moo":

===================================================

* Debian 11:

$ ip mo help
Usage: ip monitor [ all | LISTofOBJECTS ] [ FILE ] [ label ] [ all-nsid ]    
[ dev DEVICE ]
OBJECTS :=  address | link | mroute | neigh | netconf |
            nexthop | nsid | prefix | route | rule | stats
FILE := file FILENAME

* Debian 12:

$ ip mo help

 _ __ ___   ___   ___
| '_ ` _ \ / _ \ / _ \
| | | | | | (_) | (_) |
|_| |_| |_|\___/ \___/


P.S. no real cows were harmed for this moo

===============================================

I have received reports in private that this broke some scripts that uses "ip
mo" for "ip monitor".

Looking back in the packaging history, the regression is likely introduced in
https://salsa.debian.org/kernel-team/iproute2/-/commit/4aace8ca0b29535f18907b027afadd51d155ea4f
.

Could you please look into it and possibly revert to old behavior in Debian
12?


Thanks,
Boyuan Yang
