Bug#1079374: debootstrap: Needs to look through Provides

[Samuel Thibault <sthibault@debian.org>]

Package: debootstrap
Version: 1.0.137
Severity: important

Hello,

As discussed in bug #1076045, currently Debian Hurd is completely
uninstallable because:

- cron depends on cron-daemon-common
- cron-daemon-common depends on systemd | systemd-standalone-sysusers | systemd-sysusers
- but obviously systemd is not available on Debian Hurd.

It happens that opensysusers, available on Debian Hurd, provides
systemd-sysusers, but debootstrap is not smart enough to notice that.

This dependency is coming from the dh_installsysusers helper. I proposed
adding | systemd-sysusers there, but apparently the debhelper maintainer
does not want this solution on the long run, and says that it's up to
debootstrap to get smarter. Is it possible in a short enough term?
Otherwise, what possibility do we have? Ask opensysusers to actually
ship a systemd-sysusers package on non-Linux?

Samuel
