Hi, In test_filechanged.vim, those three parts are the sources of fail:
https://github.com/vim/vim/blob/master/src/testdir/test_filechanged.vim#L15-L18 https://github.com/vim/vim/blob/master/src/testdir/test_filechanged.vim#L57-L60 https://github.com/vim/vim/blob/master/src/testdir/test_filechanged.vim#L76-L79 nanotime feature: Compiled with sub-second time stamp checks. I think we can disable the 'nanotime' feature in the Debian build stage, or extend the filesystem so it supports sub-second time stamp. Not sure if it's what the entry of 'Extend ext2fs to support 64bit time.' in the TODO list means. Best, Zhaoming
