There's got to be a better way to do this though... @ronald: The reason is, /var/run holds the pids of all the running services, so mounting /var/run in RAM lets you avoid “server didn’t terminate properly, so initscripts still thinks it’s running”.

S 0:00 /bin/sh /usr/bin/mysqld_safe 5072 ? Sl 0:00 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --skip-external-locking --port=3306 --socket=/var/run/mysqld/mysqld.sock (K)Ubuntu of course. My idea is that you configure MySQL to store logs somewhere else. /etc/mysql/my.cnf : log_bin = /var/log/mysql/mysql-bin.log Change it if you want. Filesystem Size Used Avail Use% Mounted on
varrun 506M 176K 506M 1% /var/run

And I run MySQL like so:
5032 ? S 0:00 /bin/sh /usr/bin/mysqld_safe
5072 ? Sl 0:00 /usr/sbin/mysqld –basedir=/usr –datadir=/var/lib/mysql –user=mysql –pid-file=/var/run/mysqld/mysqld.pid –skip-external-locking –port=3306 –socket=/var/run/mysqld/mysqld.sock

/etc/mysql/my.cnf : log_bin = /var/log/mysql/mysql-bin.log
Change it if you want.
