Hi, I am writing a frontend for pacman that displays messages for each PM_TRANS_EVT_SCRIPTLET_INFO received. I recently noticed that only stdout gets piped through alpm to the scriptlet info event. For example, when upgrading my kernel with pacman I usually get a warning message from LZMA during mkinitcpio. This warning was not displayed in my frontend, so I wondered if this could be fixed in alpm.

The easiest solution I can think of is to add a redirection ("2>&1" I think) to the end of cmdline in _alpm_runscriptlet (in trans.c). However, this might not be the best one as it would mean that stdout and stderr would be indistinguishable to the frontend. It also might be nonstandard shell syntax, so popen might not handle it correctly (I'm not sure). Anyway, if something could be done about this I would appreciate it.
