No. This is outside the realm of LTP, but we must remain conscious of the fact that there are folks running LTP on cellphones, etc, where space is very much a luxury. > 3. A kind of seperating tag is needed for kernel message, right? e.g > <kernel_dump_start>dump message<kernel_dump_end> I think that adding an optional capture feature might be worthwhile, but you'll no doubt quickly find with some processes that the dmesg buffer will fill up quickly. > 4.

Can you say that with 100% certainty? One of the potential problems with system is the fact that it allocates a shell and depending on how processes are executed and how file descriptors are cleaned up, Actually, pan makes zero attempts at closing open file descriptors and the like, so the problem is still very much with pan. > if not use system(3), can you give your suggestion on this, exec(3) seems to > have the same problem as system(3)? Yes and no. In this case the problems that exist with open file descriptor inheritance, etc are unfortunately no worse from that perspective than your proposed code would do, but there are still other problems that need to be resolved with your proposed change anyhow that are much more pressing. -Garrett ------------------------------------------------------------------------------ Beautiful is writing same markup.
