If there is a net.* service started (other than net.lo), MySQL will fail to start with not so much as an error message. It doesn't help that the logs are rather cryptic and appear unrelated to the actual error at hand. Surely this should depend on the loopback connection specifically. I'm not sure if it still needs the rest of net for the initscript. Reproducible: Always Steps to Reproduce: 1. Stop net.lo 2. Attempt to start mysql 3. Puzzle over logs Actual Results: # /etc/init.d/mysql start * Starting mysql ... * Starting mysql (/etc/mysql/my.cnf) * MySQL NOT started (0) [ !! ] Expected Results: I was expecting net.lo to be pulled in as a dependency. I removed net.lo from the boot sequence as it was locking with udev. I'm thinking it really belongs in 'default'? I'm not sure exactly. Advice there might also be appreciated.

Well, get back to us please.
Sorry, I had almost completely forgotten about this issue. I had been needing to physically move the box around a lot, and it had proved quite annoying, but it's been up 68 days until today, when I rebooted it to get more info. I'm pretty sure it's mostly that the boot process (and shutdown) are pretty messed up. # rc-update show alsasound | boot bootmisc | boot checkfs | boot checkroot | boot clock | boot consolefont | boot default gpm | default hostname | boot hotplug | default keymaps | boot local | default nonetwork localmount | boot modules | boot mysql | default netmount | default ntp-client | default numlock | default rmnologin | boot sshd | default syslog-ng | default urandom | boot vixie-cron | default With net.lo added to boot, the boot sequence goes something as follows: * Setting user font ... (I have to ^C here) * ERROR: net.lo caught an interupt * ERROR: cannot start net.eth0 as net.lo could not start [a few other steps] * Starting gpm ... (completely hangs here) Without net.lo (which requires chrooting from a livecd to change, so I'm not inclined to do too much testing...): * Setting user font ... (I have to ^C here) * ERROR: net.eth0 caught an interrupt [continues booting to login shell] I can manually start all of these services, but I don't know why it's breaking on boot. For what it's worth, it also hangs on stopping cupsd while shutting down. I do find it interesting that sending an interrupt stops the next process, so I'm not exactly sure what it's hanging on.g
please setup RC_BOOTLOG on your system and provide the logfiles. the mysql init scripts do correctly specify 'use net', to indicate that they can use the network, but in many cases don't actually need it (unix sockets instead).
to exclude a potential other bug that may have been causing this strangeness for you, please upgrade to mysql-5.0.40 and retest.
Once again, please get back to us.
