Additionally, can we let pm-utils return one descriptive message about the
reason for the failure, if one is present? Nothing very verbose, just
something like 'Module xz failed to unload' (just an example, of
course). This would be something that can be shown to expirenced users.
Certainly, I'm not opposed to that, patches welcome. Synchronous
failures, however, are not very common
Yes, we should definitely add a HAL method to get the output.
There's a small technical obstacle insofar that method calls on the
non-standard interfaces on HAL implemented by running a binary can only
returns integers (not true for addons, they can return anything they
want). This is probably something that is fixable though. I'll look into
this.
We should definitely use the pm-utils logfiles for this. I will send a
logging hook to the pm-utils list in a few minutes.
The stuff in HAL will still write a preamble (with e.g. /sbin/lsmod
output) and possibly a postamble too. I think that belongs in HAL, not
pm-utils, because HAL provides the asynchronous error handling, pm-utils
does not.
