Addendum to readme: Downloading bootstrap files over and over again is a waste of time

Saving and Using Bootstrap Files

The instructions on saving the bootstrap files appear to be incomplete, as they seem to only grab the "precise" release version of the files.

It seems this command allows you to get bootstrap files of any release you desire stored in your ~/Downloads folder -- IF you include the releasename...

sudo sh -e ~/Downloads/crouton -d -f ~/Downloads/myreleasenamebootstrap.tar.bz2 -r releasename

substituting "releasename" above with raring, precise, quantal, etc.

Then use it like this:

sudo sh -e ~/Downloads/crouton -f ~/Downloads/myreleasenamebootstrap.tar.bz2 -t desktopname -n foldername

with "desktopname" being kde, unity, gnome, etc.

Where I'm unclear [EDIT - not anymore - see below by +Dennis Lockhart!] is whether you can use these for -u updates like this:

sudo sh -e ~/Downloads/crouton -f ~/Downloads/myreleasenamebootstrap.tar.bz2 -n foldername -u

or whether that defeats the update by using old bootstrap files???-

For updating, just leave out the -f ~/Downloads/myreleasenamebootstrap.tar.bz2 and simply update the folder name.

sudo sh -e ~/Downloads/crouton -n foldername -u

[... as it turns out, according to dnschneid, "Actually, when you update a chroot it skips the bootstrap stage entirely, as it's not necessary. The -f parameter is simply ignored, and new versions of crouton can all use the same bootstrap file, no matter how old." ]
