[CALUG] GCC Woes

[James Ewing Cottrell 3rd]

I'm not sure that mrproper is all that useful anymore. Always save any 
config file you like, and then you can use make oldconfig to get back to it.

I am also leery of trying to mix toolchains/environments without simply 
slam dunking them. You see, I once wanted a newer kernel (I think it was 
from Fedora 1[0-2] to use on RHEL5), but then it wanted a newer mkinitrd 
package, and that depended on newer init.d packages, and I ended up in 
Dependency Hell.

You make have to use --nodeps to make it work, and maybe it will, or 
maybe it won't. Heck, we glued a RHEL4 kernel onto Slackware 7 and 9 
back in 2005.

Your best bet might be to find a distro with the right version kernel 
you want, build it there, and then shoehorn it into your new distro.

And don't forget to make backups first.

P.S. Bryan's ide of a chroot jail is good too
