git repo on NTFS mount

["Lukas Schubert" <lukas.schubert@gmx.de>]

Hi there,

for historical reasons, I keep the data that doesn't belong to any
specific user on a harddisk that is formatted as NTFS. Some git
repositories are there, too. Some time ago, I upgraded from Linux Mint 17
to 19.2. That upgrade brought a change in data partition's mount options.
Old:
UUID=20D0WHATEVER	/mnt/DATA	ntfs	defaults,nls=utf8,umask=000,uid=1000,windows_names
New: UUID=20D0WHATEVER	/DATA		ntfs	defaults,umask=007,gid=46

Now I want to initialize a new git repository
user@xxxx:/DATA/Projects/LearnPython/wxGlade$ git init
error: chmod on /DATA/Projects/LearnPython/wxGlade/.git/config.lock
failed: Operation not permitted
fatal: could not set 'core.filemode' to 'false'

Since there already are repos on that drive, the initialization must have
worked before. But in
https://www.linuxquestions.org/questions/showthread.php?p=6074034#post6074034
I've been told that using git in linux with repositories on NTFS is a
recipe for disaster.

Given I change the mount options to what worked before the update, can I
escape certain doom if I stick to a certain subset of git commands? Or is
the cathastrophe inevitalbe due to subtle errors that culminate but stay
hidden until it's too late?

Thanks


Lukas
