Currently, OS is ubuntu 22.04. I'm confident that the distribution does not make a difference. Following section of the code should be skipped for given case. https://github.com/git/git/blob/master/config.c#L3434-L3438 if (chmod(get_lock_file_path(&lock), st.st_mode & 07777) < 0) { error_errno(_("chmod on %s failed"), get_lock_file_path(&lock)); ret = CONFIG_NO_WRITE; goto out_free; } I'm looking for some advice how to best skip or catch this section. In addition, I came across this Netapp setting which might just ignore the chmod operations without Client side failure. I haven't tested it yet. https://kb.netapp.com/on-prem/ontap/da/NAS/NAS-KBs/Can_I_set_UNIX_style_permissions_from_an_NFS_mount_on_an_NTFS_qtree Thank You Josef
