This is purely for implementation simplicity - a hard link is used. However, it makes it difficult to use when the main log files live in ramdisk and one wants to preserve them in FLASH. Given that in many cases the logs are compressed as they are being rotated, using hard links doesn't buy much anyway. 18842 1 liezhi.yang 2012-03-02 08:45:41 +0000 Hi Gary, I think this is because the logrotate uses: rename(const char *oldpath, const char *newpath); to rotate the log, the rename can't acrosses the different filesystems, I will use read and write to replace the rename if you are OK with it, and will send the patch review next week after enough testing. 18924 2 richard.purdie 2012-03-08 20:45:30 +0000 Fixed in http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=d7663ff7ab2e5ef5c913befad5e0adfbd6cc22a2 18960 3 liang.li2 2012-03-12 01:42:15 +0000 verified it on : git info:6bd23e0faf329f086bb4885991ce5f5d095dac56 git branch: poky/master use following steps: 1. set build env,run "source ./oe-init-build-env builddir". 2. add lines to the conf/local.conf of builddir.
