Fedora 11 Boot-Time
To reduce boot time, the setroubleshoot daemon and several small bottlenecks were removed. Regressions in using the readahead service were removed by setting low I/O priorities. Readahead now profiles the system every time the rpm database changes.
Disabling graphical boot (Plymouth)
When troubleshooting problems with graphical boot, one step is to disable the kernel mode setting feature.
Adding nomodeset to the kernel boot prompt in grub disables modesetting. This can be specified during normal boot by entering the GRUB menu and appending nomodeset to the line that begins kernel /vmlinuz.... It can be disabled in configuration by adding the nomodeset option to the same line in /etc/grub.conf.
If you are having problems with the graphical boot, be sure to file or comment on an existing bug report at https://bugzilla.redhat.com/enter_bug.cgi?product=Fedora under the plymouth component.
