Subject: uswsusp: resume_device set to devfs-like name (under D-I),
always prevents hibernation
Date: Fri, 16 Mar 2007 10:23:43 +0100

Package: uswsusp
Version: 0.3~cvs20060928-6
Followup-For: Bug #411727


Hello,

I recently tested Etch on a few laptops and I noticed the uswsusp resume_device was always
set to long device (devfs like) names.

I first assumed It was a well known bug for Etch installation, but it doesn't seems so. Is it?
Do you think it means that it will prevent hibernation to work by default for Etch on laptop ?

My understanding is that :
- uswsusp is installed under the D-I environement ('Laptop' task depends on it).
- The D-I environnement uses devfs long names.
- so uswsusp configures swap device using devfs.
- therefore s2disk doesn't work.

Let me know if i can help. I start digging on how grub-install works.

Would it be better to:
- add a hook in the current package, in order to detect that we're in D-I, then use di's mapdevfs.
- or to have a standalone uswsusp_install.udeb package
(there are probably other solutions)

Workaround for affected users :
Run "dpkg-reconfigure uswsusp" after reboot fix the problem.
