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
