The rpc.statd and rpc.mountd allocates memory according to
RLIMIT_NOFILE, so decrease it to 4k to keep sync with sysvinit
Hi Richard,
This patch could fix the test_image failure with systemd. Would like to
try systemd as default init manager on yocto build again
to check whether any more blocking issues?
Thanks,
Kai
After applying the patch, the memory cost is the same with sysvinit:
