Create a backup kernel

Stuart Powell — Wed, 05 Feb 2003 18:29:37 GMT

I've got a good copy of a tuned kernel and want to make a backup copy. What are the steps?
Is it as easy as "cp -p /stand/vmunix /stand/vmunic.prev"? With a similar comand for /stand/system.

thanks

Stuart,

Yes, it's as simple as that - that's exactly what SAM does if you use it to build a kernel.

Stuart,

I should add that you probably want to do the same thing with the /stand/system file.

You can not boot off a kernel stored on a non HFS filesystem.

You can howeer store backups anywhere you want, if you are short of space on /stand

Hi Stuart,

Yes, it's that easy, but I'd caution you to use another extension than .prev as that's what's used by default.
So that the next time you build a kernel your cuurent kernel is cp'd to .prev.
If you want to *permanently* save this kernel rename them to vmunix.safe / system.safe & then they'll never be overwritten.

My 2 cents,
Jeff
