I am getting ready to re-install XP and I would like to avoid having to
completely redo my cygwin install. Is there a way to export the current
settings (installed packages, etc) and then re-import it after re-install?
I was thinking of just copying my cygwin_install directory that has
setup.exe and the mirror folders and then reintroducing that to the new
install, or just copying the entire cygwin root folder as well.
Is there a prescribed method for this?

Barring a backup utility to restore it later, I would suggest a
straight copy to an external disk or perhaps burn it on a DVD. Be
sure to export a copy of the registry so you can later import it.

So the only reason to care much about the registry is if you want cygcheck
to be able to report where your Cygwin installation is. This can be nice
if you need to send your cygcheck information in when getting help from the
list but it would also presuppose that you put Cygwin right back in the
same location as in your current installation.
While I would also tend to just copy off my current Cygwin install and then
plop it back in when I finished the O/S reinstall, there will be things
like local user and group accounts in '/etc/passwd' and '/etc/group' that
will need updating. A reinstall of Cygwin avoids some of these little
clean-up tasks that come from just copying over a previous installation.

Would one be able to re-execute the post install scripts to manage it?

Well, in the case of the '/etc/passwd' and '/etc/group' files, not entirely.
000-cygwin-post-install.sh will create these files but only if they don't
exist already.

Not sure if the following will work, but couldn't you use something like:
Old machine: cygcheck -cd package_list.log
New machine: setup --packages < package_list.log
You would have to copy your home directory and possibly massage the input data.

If you do the old standard,
mkpasswd -l > /etc/passwd
mkgroup -l > /etc/group
will that take care of it, or would I need to delete what is in those
directories now first?
The location of the cygwin directory will be the same. Is there a list
of the windows registry entries for cygwin? I will not want to re-import
the entire regisrry, so it would be nice to be able to make up a little
batch file that would just insert the entries related to cygwin.

For these files, your above recipe will work.

As the FAQ that I pointed to said, there's nothing in the registry Cygwin
needs to work.

Just pack up the installation directory, and splash it somewhere afterward.
You'll have to regen the /etc/passwd and /etc/group, unless you're running in
domain environment.
On an unrelated note, install Cygwin on a separate partition next time. :)

Totally unnecessary. If you've maintained your installation for quite some
time, updating regularly, then setup cache contains lots of obsolete packages.
Would be much, much faster to just burn it and download new setup.exe when you
need it.

So I will just tar up the cygwin directory and put it back after the new
install. If I download a new copy of setup.exe and point it at the
install directory, will it figure out what packages are already
installed? I suppose I could test this sort of thing, but I figure that
someone already knows the answer. Is there any reason to not re-use my
current version of setup.exe, minus that setup cache? I think it is
pretty recent.
In the other thread, you asked me to not "top post". I'm not familiar
with that term, so I'm not sure exactly what I need to avoid. I believe
that I replied to the last post in the thread to make my post. I do try
very hard to comply with proper posting procedures, so I would
appreciate some clarification.

this sound to me that I made a mistake.
I typically when got a new pc, or a new installation of OS, just
download setup.exe
and install "ALL" a/v package, in order to ease the future usage.
but now it typically takes 1 or 2 days to finish, considering also
install cygwin port packages...
I'll install based on a "install-on-need" base...next time.
b.t.w., comparing with a "real" linux, like ubuntu, the current cygwin
package maintenance tool
seems still in the raw stage , comparing with apt-get machanism ... not
to complain..

Yes. The list of packages is in /etc/setup/installed.db, as best I can
tell. Other setup information is in there as well.

It might still be out of date. Who knows. I always use the latest setup
version when upgrading my Cygwin packages; I don't even keep a local copy of
it.
