[Bug 697792] Re: permissions of /etc/fuse.conf are reset on upgrade

[Goswin von Brederlow]

FYI the fix is wrong. It destroys the idempotency of postinst. If the
postinst is interrupted after the addgroup call then a repeated
invokation of the postinst script will not change the mode or ownership
of /etc/fuse.conf.

This also applies when fuse-utils was installed in the past, then was
purged and is now installed again. In that case the group already exists
but the conffile does not.


Instead of testing for the existance of the fuse group the postint script should check wether it is a first install ($2 is empty) or an upgrade ($2 is old v ersion).

  Binary package hint: fuse-utils

  The fuse-utils postinst unconditionally resets the permissions of
  /etc/fuse.conf to 0640 root:fuse. It should respect local
  modifications to the conf file.
