I've got FC15 installed. Boot time was initially normal, but it now takes over 30 minutes to boot. I may have caused this problem with a lazy test program.
During boot I see the delay at point marked *DELAY* in this partial /var/log/boot.log:
...
Started /home.
Started Reconfigure the system on administrator request.
Started Mark the need to relabel after reboot.
Starting Enable all detected swap partitions...
Started Relabel all filesystems, if necessary.
Starting Recreate Volatile Files and Directories...
Starting Tell Plymouth To Write Out Runtime Data...

This information lead me to check the /tmp directory. I initially found it full of hundreds of thousands of files (mostly empty) that were created by a lazy test program that I had been using.
Deleting those files took quite a long time, but did nothing to improve the boot time.
The size information for /tmp is a bit strange, but I am not familiar with what is normal for the directory:

The /var/log/messages has one note about tmp.mount:
/var/log/messages:Jul 27 08:28:49 localhost kernel: [35660.007323] systemd[1]: tmp.mount mount process exited, code=exited status=1
/var/log/messages:Jul 27 09:03:43 localhost kernel: [ 0.399448] devtmpfs: initialized
The file shows the delay as well (the tmp.mount message above is the 19th below):
The /var/log/boot.log file does show one failure, but it occurs well after the delay:
...

Started LSB: start and stop xinetd.

...
Is there a more effective way to clean out the /tmp directory?
Is there a way to determine more about what the /var/log/messages tmp.mount message is complaining about?
Is there anything else I should look at for clues?
