Upgrading libc6 from etch to testing.Too Risky?

I want to upgrade my libc6,from etch to testing,the output of apt-get below: Reading package lists... Building dependency tree... The following extra packages will be installed: binutils libc6-dev libc6-ppc64 libncurses5 libncurses5-dev libselinux1 libslang2 linux-libc-dev locales tzdata util-

Upgrade to Etch is now OK,but with a small problem.

I am tuning my new Etch system,I have finally installed using a small HFS partition on the harddisk and a netinstall ISO in a flash key.The problem is: I cannot boot anymore my MacOS 9.2.2 partition,when I try booting from a CD the MacOS on it does not even recognize the 2 HFS+ and HFS on the hardd

Fresh harddisk install of Etch,after the upgrade 3.1/4.0 with apt-get failed.

The upgrade from 3.1 to Etch using apt-get went very bad,now I don´t even have access to the system,the login prompt freezes when I do the login.Now I´m thinking about doing a hard disk based fresh install of Etch.

I want to upgrade to the latest Sarge r7 and then upgrade to Debian 4.0r2 and I am not sure about two things: 1) I installed apt_0.5.28.6 and aptitude_0.2.15.9-2 (from Sarge r7) and I don´t know if they do the security checks.Check Release.gpg and then the md5 automatically.I have the idea t

Need to configure manually PPPoE,PPP,pppoeconf does not work for me.

pppoeconf is useless for me,when I run it detects eth0 but after some checks it outputs: Sorry,I scanned 1 interface but the access concentrator of your provider did not respond.Please check your network and modem cables.Another reason for the scan failure may also be another running pppoe proces

USB flash key and other issues.

1)I have a USB flash key of 1Gb but my DebianPPC-kernel 2.6.8 when booting recognize the key,the seller(Verbatim), etc. but when I try to mount the key I can´t find a filesystem to do so: msdos,vfat etc. are not good,I receive a warning saying that can´t find a FAT filesystem on the key.In MacOS9.2
