Re: Windows based installation of Fedora Linux?



Perhaps then, if someone with the skill to work on the Linux side of the stuff can figure out how to solve some of the issues, the patches could be sent into the upstream for affected components, and I do have some knowledge of NSIS, but Wubi code is somewhat difficult for me to sift through.... So how does the latest version of the installer work exactly? I am somewhat confused now....

I am no fs expert, but my understanding is:

nested filesystem => forget about the journal in the nested fs

I may be wrong, but I'd guess that VMs suffer the same problem, and the hosted
fs journal can also get corrupted in case of a hard reboot of the hosting
system.

In short I would expect Wubi I/O behavior/performance to be on par or better
than a VM, under all scenarios. BUT in a VM under windows you would use windows
fs driver for the hosting system, while we use ntfs-3g/vfat. So the above
statement assumes that ntfs-3g/vfat behaviour/perfomance is equivalent to the
windows counterpart.

You can always tweak the scripts affecting sysctl

Should be both since that affects the kernel.

Yes Ubuntu kernel hackers have been looking into this, there was just no time
to do it for the 7.10 release, it will probably be fixed for the next release.
But that is beyond my skills.
