Replacing one (1) kext

[limini]

When it come to handling the terminal in osx, so far I've definitely been a monkey (tell me what to type and I'll type it). Now I'm trying to "solo" and replace the AppleSMBIOS.kext on my system with Netkas'. The code I commonly see involving these kexts involves backing up and replacging using the cp "-R" flag which according to the info I've found means"

Copy the folder and subtree: Symbolic links will be copied not indirected through. cp will create special files rather than copy them as normal files. Created folders have the same mode as the corresponding source folder, unmodified by the process' umask.

Hmmm. That seems to imply that this won't work:

 cd /Volumes/bootloader/pc_efi_80
cp -R /AppleSMBIOS.kext /system/library/extensions/

Will it work if I omit the "-R"? If not what's the correct code for this?

 

Also: is it necessary to do this after a kext is replaced:

rm -rf / system/library/extensions.*

to let the system rebuild its kext cache?

 

My vanilla 10.4.11 upgrade is working fine. I never did do the "kext refresh": is it possible that some kexts may not be rebuilt and that this will bugger up the current installation by eliminating kexts that are essential for my machine and that won't be "regenerated"?

 

Thanks for any help.
