Created attachment 557088 [details] emerge --info On a fresh install of =dev-db/mysql-5.7.24, running emerge --config fails due to root:root 755 perms on /var/run/mysqld. Changing ownership to mysql:mysql fixes the issue as described here: https://stackoverflow.com/questions/34954455. I see the following in mysql-5.7.24.ebuild: # Now that /var/run is a tmpfs mount point, we need to ensure it exists before using it PID_DIR="${EROOT%/}/var/run/mysqld" if [[ ! -d "${PID_DIR}" ]] ; then install -d -m 755 -o mysql -g mysql "${PID_DIR}" || die "Could not create pid directory" fi which may suggest that the directory is somehow created before the check for its existence, and the install command is never run. A check for correct perms in addition to existence may be the solution, though I have not tested that yet.
>=dev-db/mysql-8 will check for that and _report_ the problem (https://gitweb.gentoo.org/repo/gentoo.git/tree/dev-db/mysql/mysql-8.0.17.ebuild?id=62c4958c9adbc445838f5bb533ead2f75b22413e#n680). However, we will never adjust permission because we can't know if administrator has set this permission on purpose... No plans to backport this to <mysql-8.
