"bad" in what sense? It's hard on mirror bandwidth, and that's bad, but
it's not as likely to hose your system as a yum-upgrade would be.
I've also been pondering what anaconda work would be needed to do system
upgrades from the hard drive you're upgrading - assuming you have the
free space on your drive, you could do something like:
Start "live-updater" tool
- Checks installed packages, as anaconda does
- Downloads all updated packages
- (Alternately: use a DVD iso and it would only
download the packages you're missing.)
- Grab kernel/initrd (from mirror or DVD iso)
- update grub.conf, adding special flag(s) for anaconda
Reboot into anaconda
- Upgrade filesystems, perform other fixups that require unmounted fs
- Mount target filesystem label
- Upgrade using previously-downloaded packages / iso image
The downside is that it requires a few gigs of free drive space, but on
the plus side we don't need a separate partition for holding the
updates.
A sneaky thing we might do is:
1) download all packages
2) swapoff
3) mkfs.ext3 $SWAP_PARTITION
4) mount $SWAP_PARTITION /mnt/swap
5) copy all packages to /mnt/swap
6) get vmlinuz/initrd and update grubby
7) reboot into anaconda, upgrading from $SWAP_PARTITION
Just a thought.
