At the time the image is created, /etc/resolv.conf is already a symlink to /var/run/resolv.conf, but at boot time when populate-volatiles.sh is run, /var/run/resolv.conf doesn't exist, causing it to try to rm -f and ln -sf which of course fails due to the read-only filesystem. I would suggest to remove the readlink check on $1 as per the attached patch. 69154 1 3563 byo 2016-12-15 15:37:26 +0000 Created attachment 3563 suggested patch 69156 2 ross.burton 2016-12-15 15:59:14 +0000 That code has more backslashes than other characters!

This is with sysvinit, no systemd. I've been using Martin's patch here: http://lists.openembedded.org/pipermail/openembedded-core/2018-July/152886.html to silence them locally, but the patch never got merged, and I can't tell if the patch is correct or not. 84711 5 jacob.kroon 2019-08-19 12:07:54 +0000 Just to clarify, the warnings above is when I *don't* use Martin's patch. They go away when patch is applied. 84761 6 jacob.kroon 2019-08-29 11:45:57 +0000 Patch has been merged now: commit fb028a0a25c02ab56ad262afd8e6e9495a44673d Author: Martin Hundebøll <martin@geanix.com> Date: Wed Aug 21 12:25:53 2019 +0200 3563 2016-12-15 15:37:26 +0000 2016-12-15 15:37:26 +0000 suggested patch 0001-initscripts-populate-volatile-suppress-read-only-roo.patch text/plain 1988 byo RnJvbSAxNWM4YTEzNDBkYmNmN2ExYTc0YzE0ZmUwNzk2ZTBiYjE3YmNhZThjIE1vbiBTZXAgMTcg MDA6MDA6MDAgMjAwMQpGcm9tOiA9P1VURi04P3E/QW5kcj1DMz1BOT0yMERyYXN6aWs/PSA8YWRy YXN6aWtAdHljb2ludC5jb20+CkRhdGU6IFRodSwgMTUgRGVjIDIwMTYgMTU6MzE6MzYgKzAwMDAK U3ViamVjdDogW1BBVENIXSBpbml0c2NyaXB0czogcG9wdWxhdGUtdm9sYXRpbGU6IHN1cHByZXNz IHJlYWQtb25seS1yb290ZnMKIHdhcm5pbmdzCk1JTUUtVmVyc2lvbjogMS4wCkNvbnRlbnQtVHlw ZTogdGV4dC9wbGFpbjsgY2hhcnNldD1VVEYtOApDb250ZW50LVRyYW5zZmVyLUVuY29kaW5nOiA4 Yml0CgpybTogY2FuJ3QgcmVtb3ZlICcvZXRjL3Jlc29sdi5jb25mJzogUmVhZC1vbmx5IGZpbGUg c3lzdGVtCmxuOiAvZXRjL3Jlc29sdi5jb25mOiBGaWxlIGV4aXN0cwoKL2V0Yy9kZWZhdWx0L3Zv bGF0aWxlcyBjb250YWlucyBhbiBlbnRyeToKbCByb290IHJvb3QgMDY0NCAvZXRjL3Jlc29sdi5j b25mIC92YXIvcnVuL3Jlc29sdi5jb25mCgp3aGljaCBjYXVzZXMgcG9wdWxhdGUtdm9sYXRpbGUu c2ggdG8gZXhlY3V0ZSB0aGUgZm9sbG93aW5nIGluIGxpbmtfZmlsZSgpOgogIGlmIFsgLUwgXCIk MlwiIF07IHRoZW4KICAgIFsgXCJcJChyZWFkbGluayAtZiBcIiQyXCIpXCIgIT0gXCJcJChyZWFk bGluayAtZiBcIiQxXCIpXCIgXSAmJiB7IHJtIC1mIFwiJDJcIjsgbG4gLXNmIFwiJDFcIiBcIiQy XCI7IH07CiAgZWxpZiBbIC1kIFwiJDJcIiBdOyB0aGVuCiAgICAuLi4KCkF0IHRoZSB0aW1lIHRo ZSBpbWFnZSBpcyBjcmVhdGVkLCAvZXRjL3Jlc29sdi5jb25mIGlzIGFscmVhZHkgYQpzeW1saW5r IHRvIC92YXIvcnVuL3Jlc29sdi5jb25mLCBidXQgYXQgYm9vdCB0aW1lIHdoZW4KcG9wdWxhdGUt dm9sYXRpbGVzLnNoIGlzIHJ1biwgL3Zhci9ydW4vcmVzb2x2LmNvbmYgZG9lc24ndApleGlzdCwg Y2F1c2luZyBpdCB0byB0cnkgdG8gcm0gLWYgYW5kIGxuIC1zZiB3aGljaCBvZiBjb3Vyc2UKZmFp bHMgZHVlIHRvIHRoZSByZWFkLW9ubHkgZmlsZXN5c3RlbS4KCltZT0NUTyAjMTA4MTRdCgpTaWdu ZWQtb2ZmLWJ5OiBBbmRyw6kgRHJhc3ppayA8YWRyYXN6aWtAdHljb2ludC5jb20+Ci0tLQogbWV0 YS9yZWNpcGVzLWNvcmUvaW5pdHNjcmlwdHMvaW5pdHNjcmlwdHMtMS4wL3BvcHVsYXRlLXZvbGF0 aWxlLnNoIHwgMiArLQogMSBmaWxlIGNoYW5nZWQsIDEgaW5zZXJ0aW9uKCspLCAxIGRlbGV0aW9u KC0pCgpkaWZmIC0tZ2l0IGEvbWV0YS9yZWNpcGVzLWNvcmUvaW5pdHNjcmlwdHMvaW5pdHNjcmlw dHMtMS4wL3BvcHVsYXRlLXZvbGF0aWxlLnNoIGIvbWV0YS9yZWNpcGVzLWNvcmUvaW5pdHNjcmlw dHMvaW5pdHNjcmlwdHMtMS4wL3BvcHVsYXRlLXZvbGF0aWxlLnNoCmluZGV4IDkxNTE0YmFjODYu LmE2Nzc4MGM5M2EgMTAwNzU1Ci0tLSBhL21ldGEvcmVjaXBlcy1jb3JlL2luaXRzY3JpcHRzL2lu aXRzY3JpcHRzLTEuMC9wb3B1bGF0ZS12b2xhdGlsZS5zaAorKysgYi9tZXRhL3JlY2lwZXMtY29y ZS9pbml0c2NyaXB0cy9pbml0c2NyaXB0cy0xLjAvcG9wdWxhdGUtdm9sYXRpbGUuc2gKQEAgLTcw LDcgKzcwLDcgQEAgbWtfZGlyKCkgewogbGlua19maWxlKCkgewogCUVYRUM9IgogCWlmIFsgLUwg XCIkMlwiIF07IHRoZW4KLQkJWyBcIlwkKHJlYWRsaW5rIC1mIFwiJDJcIilcIiAhPSBcIlwkKHJl YWRsaW5rIC1mIFwiJDFcIilcIiBdICYmIHsgcm0gLWYgXCIkMlwiOyBsbiAtc2YgXCIkMVwiIFwi JDJcIjsgfTsKKwkJWyBcIlwkKHJlYWRsaW5rIC1mIFwiJDJcIilcIiAhPSBcIiQxXCIgXSAmJiB7 IHJtIC1mIFwiJDJcIjsgbG4gLXNmIFwiJDFcIiBcIiQyXCI7IH07CiAJZWxpZiBbIC1kIFwiJDJc IiBdOyB0aGVuCiAJCWlmIGF3ayAnXCQyID09IFwiJDJcIiB7ZXhpdCAxfScgL3Byb2MvbW91bnRz OyB0aGVuCiAJCQljcCAtYSAkMi8qICQxIDI+L2Rldi9udWxsOwotLSAKMi4xMS4wCgo=
