Subject: core: set $JOURNAL_STREAM to the dev_t/ino_t of the journal stream of executed services
X-Git-Tag: v231.3~97
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=d046fa2e88ab824e7dc3e32172328357779ab0f6;p=elogind.git

core: set $JOURNAL_STREAM to the dev_t/ino_t of the journal stream of executed services

This permits services to detect whether their stdout/stderr is connected to the
journal, and if so talk to the journal directly, thus permitting carrying of
metadata.

As requested by the gtk folks: #2473
