Well, I'm running setup now, installing everything, though my check
script reveals that 3 packages have problems (not the package that was
causing the problem before).
$ ~/script/md5cygchk -q /u/mirror/cygwin/release
Summary of files with broken checksums:
In ./binutils:
md5.sum: FAILED
md5sum: WARNING: 1 of 6 computed checksums did NOT match
In ./check:
check-0.8.4-1-src.tar.bz2: FAILED
md5sum: WARNING: 1 of 3 computed checksums did NOT match
In ./ncurses/libncurses5:
libncurses5-5.2-1-src.tar.bz2: FAILED
md5sum: WARNING: 1 of 3 computed checksums did NOT match
Before, it was failing after a minute (probably after it checked the
md5 sigs). Now, it's been happily installing for an hour (in fact it's
running the Cygwin postinstall scripts now).
Since I told setup to install all, would you expect setup to fail,
reporting that at least one of the above packages is broken? Because
it isn't complaining...
We first rsync-ed from mirrors.kernel.org; that has broken TeXmacs (and
more?). Following that we rsync from mirrors.xmission.com, which
replaced TeXmacs. But that still leaves us with the three problems
reported above.
What do you think of this idea, to try to get a good local mirror? (It
relies on the fact that rsync will only download missing files, so it's
not as horrendous as it may seem at first):
for each host in
ftp.gwdg.de
ftp.inf.tu-dresden.de
ftp.kaist.ac.kr
mirror.averse.net
mirrors.kernel.org
mirrors.xmission.com
sigunix.cwru.edu
do
rsync our mirror from the host
check our mirror's checksums
if check is good, break (otherwise, next in list)
Especially if we use the --update option. Unless sluggish mirrors that
were way out of date would cause deletion of newer files? Hmm, by my
reading, that wouldn't happen unless we specified --delete to rsync.
So this may be a good scheme.
