Subject: [PATCH v3] systemd: Replace use of %m in printf formats
Date: Mon, 11 Jul 2011 10:26:15 -0700 [thread overview]
Message-ID: <1310405175-4795-1-git-send-email-raj.khem@gmail.com> (raw)
The patch is applied optionally only to uclibc builds
Also move the mkostemp replacement patch to uclibc only list
Not perfect yet but gets us going on uclibc

+Patch from Henning. %m is a glibc only thing. For uclibc we need to do it
+differently. So we use static strings instead of mallocing them and free'ing
+
+I dont know if upstream systemd have plans to make systemd work on non
+glibc system libraries if not then this patch would not make sense for
+upstream
