#83499 — Bug#1078721: iproute2: removing /sbin/ip link breaks other packages and possibly user scripts

Package: iproute2
Version: 6.10.0-1
Severity: critical
Justification: breaks the whole system

The first time I rebooted after iproute2 removed the /sbin/ip link, my system
failed to boot. I eventually discovered this was because /sbin/vconfig (from
the "vlan" package) calls /sbin/ip and when that failed the network was not
configured. This meant having to boot into single user mode for diagnostics
because systemd hung forever waiting for the network.

My ideal solution would be to revert 1064795 and mark it "wontfix" as there's
no way to know how many users have locally written scripts that call ip via
what used to be a perfectly valid path (and because removing the symlink buys
exactly nothing as far as I can tell).

A less satisfactory solution would be to add a versioned Breaks and a version
of the vlan package with a different path to /sbin/ip. (And, of course, any
other package that might have broken, not including local scripts which we
can't possibly identify.)
