The existing rule would only be effective when the block drivers are compiled
|
|
as modules as opposed to being builtin. On some systems such as Guix System,
|
|
the 'sr_mod' driver for optical discs is builtin the kernel instead of a
|
|
module, and the absence of polling means there are no uevents emitted for
|
|
udisks to act on.
|
|
|
|
This change was originally contributed to Debian by Martin Pitt to fix
|
|
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=713877>, later removed as it
|
|
was deemed no longer needed. It appears still useful on eudev and elogind
|
|
systems like Guix System and others.
|
|
|
|
* rules.d/60-block.rules: Apply kernel polling to all removable devices instead
|
|
of just those of the block category handled by a kernel module.
