Revision 6c293d408dbbd0206e80df3ecda7f1620cadaa94 authored by Santi Béjar on 08 March 2008, 11:30:04 UTC, committed by Junio C Hamano on 09 March 2008, 03:43:21 UTC
The "config --global" suggested in the message is a valid one-shot fix, and hopefully one-shot across machines that NFS mounts the home directories. This knowledge can hopefully be reused when you are forced to use git on Windows, but the fix based on GECOS would not be applicable, so it is not such a useful hint to mention the exact reason why the name cannot be determined.

USAGE='[--interactive | -i] [-v] [--onto <newbase>] <upstream> [<branch>]'
LONG_USAGE='git-rebase replaces <branch> with a new branch of the
same name. When the --onto option is provided the new branch starts
out with a HEAD equal to <newbase>, otherwise it is equal to <upstream>
It then attempts to create a new commit for each commit from the original
<branch> that does not exist in the <upstream> branch.
It is possible that a merge failure will prevent this process from being
completely automatic. You will have to resolve any such merge failure
and run git rebase --continue. Another option is to bypass the commit
that caused the merge failure with git rebase --skip. To restore the
original <branch> and remove the .dotest working files, use the command
git rebase --abort instead.
Note that if <branch> is not specified on the command line, the
currently checked out branch is used. You must be in the top
directory of your project to start (or continue) a rebase.
Example: git-rebase master~1 topic
A---B---C topic A'\''--B'\''--C'\'' topic
/ --> /
D---E---F---G master D---E---F---G master

When you have resolved this problem run \"git rebase --continue\".
If you would prefer to skip this patch, instead run \"git rebase --skip\".
To restore the original branch and stop rebasing run \"git rebase --abort\".
