Recompiling libc with 2.2.x headers will cause problems, due to the
arrangement of the chown and lchown syscalls.
During the 2.1.x series of syscalls, the chown syscall was renamed
lchown (which does the same thing as the pre-2.1 chown), and a new
chown syscall was created (which follows symlinks).
The upshot of this is that a libc compiled with the 2.2.x headers will
follow the new syscall orientation, which will break some programs
expecting the old chown behavior (notably, dpkg, possibly tar). In
addition, you will not be able to use the new libc with a pre-2.2
To ease this transition, I suggest the following:
1) All programs should be examined for use of chown(), especially
those in base. Any packages which may break if chown operates on
the link instead of the file should be noted.
2) Wait until there are NO 2.0x kernel packages in the distribution.
3) Ensure that a libc6 upgrade depends on a kernel > 2.2.0, and
announces that it will not work with 2.0.x kernels.
4) compile libc with new headers, but not installed into dist. Allow
time for all programs identified in step 1 to be recompiled, then
install the whole shooting match at once.
It would probably be best to ship potato with a 2.2 kernel and a 2.0.x
headers libc, then for the next release remove all kernel 2.0.x
packages and do the header roll forward.
It just seems that caution is a better course of action, considering
