[Pkg-phototools-devel] experimental patch to libgphoto2 for udev issues

[Riccardo Magliocchetti]

Hello,

this patch should help with the tons of "my camera does not work" and 
"issues with udev" bugs found in the bts. This is marked experimental 
because i haven't tested it yet and don't know if the link should be 
placed in /etc/udev/rules.d or we should just drop the file in 
/lib/udev/rules.d like others are doing (see #586668).

Diffed on top of other changes sent to the list, please CC me since i'm 
not subscribed.

This is the commit message from the patch:

There are a lot of issues reported on Debian BTS of not handled
cameras or more in general issues with udev. Mine is not recognized
too while it should because there should be a generic rule for
ptp cameras.

Looking in /etc/udev/rules.d and in /lib/udev/rules.d i haven't
found any link to gphoto2 rules so maybe _that_ is why it's
not working. So my idea of fix is just makes thing more simple.

I've done these changes:
- force link of udev rules in every case and remove the old one
   if exists
- one user reports that moving the rule from 025 to 090 fixed the
   issue for him, i have no idea if that could make a difference,
   so move the rule later to 90 since the other scripts here are
   not using levels starting from zero.
   In upstream documentation they use 90 too.

thanks,
riccardo
