 Some people apparently upgrade the toolchain in a running LFS - but>

 The reliable method is to use the old system to build the new one ->

 Upgrading the toolchain falls into the "if it breaks, you keep both>

This subject has been broken into thwo threads so I reply in this one:

So, yes, I would like to have updated packages because of the possibility of security bugs.
I remember there was a bug in glibc when I gave up LFS, because I didn't want to rebuild everything...
I'm using gentoo and I thought updating LFS similar to it, as gentoo also doing it on-the-fly, though
I don't know its internal working...
And don't forget the learning experience of updating a full system:)

Oh, yes, I can remember that I was reading mailing lists and security pages like a mad to find out
what to update:)
