Converting native Fedora Core 11 to colinux Edit

accessing hwclock Edit

Disable the access to hardware RTC by removing the executable bit from file:

chmod -x /sbin/hwclock

Or rename the file to something like "hwclock.old".

udev: renamed network interface eth0 to eth1 Edit

  • Edit file /lib/udev/rules.d/75-persistent-net-generator.rules and set a bypass for coLinux in same way as xen or UML does it. Add the with + marked lines after the entry Xen (near line 26):

  • Edit file /etc/udev/rules.d/70-persistent-net.rules and remove all lines. You will mostly find a lot of them. Please remove them all.

Disable udev and use static /dev Edit

It's a pain, that udev needs so mutch cpu load while spawning such many processes. You can save a lot of booting time with a statically /dev, created from currently populated directory.

  • Make a copy of file "/sbin/start_udev" to have a backup (If you made mistaken).
  • Edit the file /sbin/start_udev and add some lines before the "Check SELinux status" near line 47:
Be carefully with this edit! Mistakes makes your system non usable.

  • Create a tar archive from current /dev and reboot:
cd /
tar --exclude ".udev" -czf staticdev.tgz dev

An error "tar: dev/log: socket ignored" can ignore.

Re-enable udev Edit

To have the udev running back, do follow steps. This can also do in the system maintaince mode:

mount -o remount,rw /
chmod -x /sbin/udevd

Single user mode or other RunlevelEdit

Single user mode (for system maintain) you can enter by adding single or S into coLinux config line as boot parameter. Other Runlevel can enter by adding the number, for example 1 to boot parameter
