[Pkg-sysvinit-devel] Bug#623098: initscripts: doesn't handle downgrading (dpkg: warning: unable to delete old directory '/run': Device or resource busy)

[Jonathan Nieder]

Package: initscripts
Version: 2.88dsf-13.4
Severity: wishlist

Hi,

I installed initscripts from experimental.  All seems fine (and fairly
sane; thanks!), but I haven't rebooted and I'm a bit of afraid to
since there is no sign udev is fixed yet.  So time to downgrade:

 # cupt install initscripts/sid
 Parsing Found/Fixed information... Done
 dpkg: warning: downgrading initscripts from 2.88dsf-13.4 to 2.88dsf-13.2.

Indeed, /run still exists.

Especially during this time of experimentation, it would be nice (but
certainly not required) if prerm + postrm made sure allow "upgrades"
back to the pre-/run state worked gracefully.
