Apparently nobody seems interested.
I tried to hunt it down with strace. For each created pdf file there is about
3000 lines trace.
Too big to send, but some interesting lines are there, like
8951 open("/usr/src/lyx/lyx-git/lib/images/qt_temp.wv8939",
O_RDWR|O_CREAT|O_EXCL|O_CLOEXEC, 0600) = 12
...
8951 rename("/usr/src/lyx/lyx-git/lib/images/qt_temp.wv8939",
"/usr/src/lyx/lyx-git/lib/images/math-macro-add-greedy-optional-param.pdf") = 0
...
8951
chmod("/usr/src/lyx/lyx-git/lib/images/math-macro-add-greedy-optional-param.pdf",
0600) = 0
Looks like use of qt temporary files in lyx source.
OK, try to call lyx -dbg files, to hunt the messages in
src/support/{TempFile,FileName,filetools}.cpp .
so here it is:
support/FileName.cpp (690): creating path
'/usr/src/lyx/lyx-git/lib/images'.
support/FileName.cpp (590): Checksumming
