I am attempting to get edx Devstack installed with Vagrant, and I'm on a Windows machine. I'm getting errors that appear to result from symlinks that aren't supported by Windows.
According to the edx troubleshooting guide under Dealing with line endings and symlinks under Windows, I should run the following commands in cygwin to deal with symlinks.
git rm --cached -r . && git reset --hard
git config --global alias.add-symlink '!__git_add_symlink(){
dst=$(echo "$2")/../$(echo "$1");
if [ -e "$dst" ]; then
hash=$(echo "$1" | git hash-object -w --stdin);
git update-index --add --cacheinfo 120000 "$hash" "$2";
git checkout -- "$2";
else
echo "ERROR: Target $dst does not exist!";
echo " Not creating invalid symlink.";
fi;
}; __git_add_symlink "$1" "$2"'
git config --global alias.rm-symlink '!__git_rm_symlink(){
git checkout -- "$1"; link=$(echo "$1");
POS=$'\''/'\''; DOS=$'\''\\\\'\'';
doslink=${link//$POS/$DOS};
dest=$(dirname "$link")/$(cat "$link");
dosdest=${dest//$POS/$DOS};
if [ -f "$dest" ]; then
rm -f "$link";
cmd //C mklink //H "$doslink" "$dosdest";
elif [ -d "$dest" ]; then
rm -f "$link";
cmd //C mklink //J "$doslink" "$dosdest";
else
echo "ERROR: Something went wrong when processing $1 . . .";
echo " $dest may not actually exist as a valid target.";
fi;
}; __git_rm_symlink "$1"'
git config --global alias.rm-symlinks '!__git_rm_symlinks(){
for symlink in `git ls-files -s | grep -E "^120000" | cut -f2`;
do
git rm-symlink "$symlink";
git update-index --assume-unchanged "$symlink";
done;
}; __git_rm_symlinks'
git config --global alias.checkout-symlinks '!__git_checkout_symlinks(){
POS=$'\''/'\''; DOS=$'\''\\\\'\'';
for symlink in `git ls-files -s | grep -E "^120000" | cut -f2`;
do
git update-index --no-assume-unchanged "$symlink";
if [ -d "$symlink" ]; then
dossymlink=${symlink//$POS/$DOS};
cmd //C rmdir //S //Q "$dossymlink";
fi;
git checkout -- "$symlink";
echo "Restored git symlink $symlink <<===>> `cat $symlink`";
done;
}; __git_checkout_symlinks'
git rm-symlinks
I have also tried the commands in the SO answer to Git symlinks in Windows, which produces the same results.
Output:
The output I get after running the above commands is a little odd, so I'm not sure if the script is successful.

Why does it go into the Windows-style command prompt at the end? This is where I'm unsure if the git commands are working.
In Vagrant:
After running vagrant up and vagrant ssh, I get the following errors when running paver devstack lms (similar output for paver devstack studio):
vagrant@precise64:~$ sudo su edxapp

From what I understand, this is a problem with symlinks (See this post on Google groups).
Am I running the above symlinks script properly? How can I check if the symlinks have been dealt with successfully?
Other attempts:
Following the suggestions in the google group (link above), I have also made the following adjustments:
After multiple vagrant destroy and vagrant provision's, I still have the same IOError: [Error 20] Not a directory problem. Any help would be much appreciated!

I think the problem is caused by your cydrive path is wrong.
Try to change in c:\cygwin\etc\fstab
none /cydrive cygdrive binary,posix=0,user 0 0
to
none / cygdrive binary,posix=0,user 0 0
refs: https://cygwin.com/cygwin-ug-net/using.html#cygdrive
UPDATE:
From CMD Type 'bash' and then copy/paste the contents of the script
If you get the same result try:
Open .gitconfig (with Notepad++ or similar) and add this section if it is not yet existing
[alias]
add-symlink = "!__git_add_symlink(){\n dst=$(echo \"$2\")/../$(echo \"$1\"); \n if [ -e \"$dst\" ]; then \n hash=$(echo -n \"$1\" | git hash-object -w --stdin); \n git update-index --add --cacheinfo 120000 \"$hash\" \"$2\"; \n git checkout -- \"$2\"; \n else \n echo \"ERROR: Target $dst does not exist!\"; \n echo \" Not creating invalid symlink.\"; \n fi; \n }; __git_add_symlink \"$1\" \"$2\""
rm-symlink = "!__git_rm_symlink(){\n git checkout -- \"$1\"; link=$(echo \"$1\"); \n POS=$'/'; DOS=$'\\\\\\\\'; \n doslink=${link//$POS/$DOS}; \n dest=$(dirname \"$link\")/$(cat \"$link\"); \n dosdest=${dest//$POS/$DOS}; \n if [ -f \"$dest\" ]; then \n rm -f \"$link\"; \n cmd //C mklink //H \"$doslink\" \"$dosdest\"; \n elif [ -d \"$dest\" ]; then \n rm -f \"$link\"; \n cmd //C mklink //J \"$doslink\" \"$dosdest\"; \n else \n echo \"ERROR: Something went wrong when processing $1 . . .\"; \n echo \" $dest may not actually exist as a valid target.\"; \n fi; \n }; __git_rm_symlink \"$1\""
rm-symlinks = "!__git_rm_symlinks(){\n for symlink in `git ls-files -s | grep -E \"^120000\" | cut -f2`; \n do \n git rm-symlink \"$symlink\"; \n git update-index --assume-unchanged \"$symlink\"; \n done; \n }; __git_rm_symlinks"
checkout-symlinks = "!__git_checkout_symlinks(){\n POS=$'/'; DOS=$'\\\\\\\\'; \n for symlink in `git ls-files -s | grep -E \"^120000\" | cut -f2`; \n do \n git update-index --no-assume-unchanged \"$symlink\"; \n if [ -d \"$symlink\" ]; then \n dossymlink=${symlink//$POS/$DOS}; \n cmd //C rmdir //S //Q \"$dossymlink\"; \n fi; \n git checkout -- \"$symlink\"; \n echo \"Restored git symlink $symlink <<===>> `cat $symlink`\"; \n done; \n }; __git_checkout_symlinks"
This will create some git commands for symlinks
Note: File uses Unix line endings, don't edit with windows Notepad!
Then execute the commands
git rm --cached -r .
git reset --hard
git rm-symlinks
I tested it in my env and it works
