Can you be more specific when sysctl with tst_net_run does not work?

+1. If really requested please create C binary testcases/lib/tst_sysctl.c.
Code which use simple SAFE_FILE_PRINTF() as many C code does would be fairly
simple, more portable and probably faster than shell script. FYI we tend to
rewrite shell code into C.

Kind regards,
