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.
