(Since this is not cleaned in any other way, the list of rpm-tmp files just keep growing until our developers face "out of free space" issues, because of no more free inodes.) By patching rpm to make the removal unconditional, the problem goes away, but probably not the prettiest fix. Attaching such a patch only for reference. This behavior was seen at least on Rocko and master (poky 0beae33, current at the time of writing). 80839 1 olof.johansson 2018-06-20 09:21:10 +0000 Forgot to mention: the leakage seems to happen during do_rootfs for RPM based images. 80881 2 richard.purdie 2018-06-21 14:42:34 +0000 Hi, I think the best solution would be to apply this patch against rpm-native only. Could you send the patch please? 80890 3 olof.johansson 2018-06-21 15:49:33 +0000 Sure thing! I'll take a look at it on Monday, if not before. Happy midsummer... :-) 80918 4 olof.johansson 2018-06-25 12:35:37 +0000 Patch submitted! 81012 5 olof.johansson 2018-07-05 11:43:44 +0000 After with discussion with Alexander Kanavin, a variant of the patch I attached was accepted and is now integrated on master (poky 6d3617). The cause of this issue was related to how OE "chroots" rpm into the target sysroot, but this is not possible for all pre/postinst scriptlets, so the chrooting is avoided in this case. That leaves rpm writing tmp files in the host's /var/tmp. We now remove them even if we are running with debug output from rpm. 4327 2018-06-18 09:14:37 +0000 2018-06-18 09:14:37 +0000 Always remove written tmp scriptlets 0001-Always-remove-written-tmp-scriptlets-even-with-debug.patch text/plain 1021 olof.johansson RnJvbSBiNzRiNTQ5ZmY2MWFiOGEyYmRiMDQxZmViYmUxMzVhZDEwZmEzMDNjIE1vbiBTZXAgMTcg MDA6MDA6MDAgMjAwMQpGcm9tOiBPbG9mIEpvaGFuc3NvbiA8b2xvZmpuQGF4aXMuY29tPgpEYXRl OiBTdW4sIDE3IEp1biAyMDE4IDEyOjEyOjM2ICswMjAwClN1YmplY3Q6IFtQQVRDSF0gQWx3YXlz IHJlbW92ZSB3cml0dGVuIHRtcCBzY3JpcHRsZXRzLCBldmVuIHdpdGggZGVidWdnaW5nCiBlbmFi bGVkCgpBcyBkZWJ1Z2dpbmcgaXMgZW5hYmxlZCBieSBkZWZhdWx0IGluIG9wZW5lbWJlZGRlZCwg YW5kIGVhY2ggc2NyaXB0bGV0CmlzIHdyaXR0ZW4gdG8gL3Zhci90bXAvcnBtLXRtcC5YWFhYWFgs IGEgbG90IG9mIGZpbGVzIGdldCBjcmVhdGVkLiBTbwptYW55IHRoYXQgcGVvcGxlIHJ1biBvdXQg b2YgaW5vZGVzLgoKVGhpcyBpcyBhIHF1aWNrIGZpeCB0byBhdm9pZCB0aGlzLiBJdCBkb2VzIGRl Z3JhZGUgZnVuY3Rpb25hbGl0eSBmb3IKdGhvc2Ugd29ya2luZyB3aXRoIGRlYnVnZ2luZyBwcmUt L3Bvc3RpbnRhbGwgc2NyaXB0cy4KClVwc3RyZWFtLVN0YXR1czogaW5hcHByb3ByaWF0ZSBbT0Ug c3BlY2lmaWNdClNpZ25lZC1vZmYtYnk6IE9sb2YgSm9oYW5zc29uIDxvbG9mam5AYXhpcy5jb20+ Ci0tLQogbGliL3JwbXNjcmlwdC5jIHwgMyArLS0KIDEgZmlsZSBjaGFuZ2VkLCAxIGluc2VydGlv bigrKSwgMiBkZWxldGlvbnMoLSkKCmRpZmYgLS1naXQgYS9saWIvcnBtc2NyaXB0LmMgYi9saWIv cnBtc2NyaXB0LmMKaW5kZXggOThkM2Y0MjBkLi42YmYyM2MxOGMgMTAwNjQ0Ci0tLSBhL2xpYi9y cG1zY3JpcHQuYworKysgYi9saWIvcnBtc2NyaXB0LmMKQEAgLTQzMCw4ICs0MzAsNyBAQCBleGl0 OgogCUZjbG9zZShvdXQpOwkvKiBYWFggZHVwJ2QgU1RET1VUX0ZJTEVOTyAqLwogCiAgICAgaWYg KGZuKSB7Ci0JaWYgKCFycG1Jc0RlYnVnKCkpCi0JICAgIHVubGluayhmbik7CisJdW5saW5rKGZu KTsKIAlmcmVlKGZuKTsKICAgICB9CiAgICAgZnJlZShtbGluZSk7Ci0tIAoyLjExLjAKCg==
