After many years as a contented Cygwin user, I decided to check out the new Ubuntu on Windows (UoW) product from Microsoft. I promptly ran into a nasty problem. I have filed it with the MS Feedback Hub, but I thought I should post here as well.
When a file is created under Cygwin, it can neither be read nor written by UoW. Any attempt to do so returns EACCES. It does not matter whether the UoW user is root or not, and it does not matter what the file permissions are as seen by UoW, or whether the file is in the UoW root (which is really C:\Users\<username>\AppData\Local\lxss\rootfs) or elsewhere on C: (which is mounted by UoW at /mnt/c). It also does not matter who has written to the file (Win32, Cygwin, or UoW). Directories are not affected by this problem. Is Cygwin creating ordinary files with some kind of magic that's different from creating a file, say, by output redirection in cmd.exe, or in a Win32 application? This is not about file names with funny characters, either. -- John Cowan http://www.ccil.org/~cowan co...@ccil.org C'est la` pourtant que se livre le sens du dire, de ce que, s'y conjuguant le nyania qui bruit des sexes en compagnie, il supplee a ce qu'entre eux, de rapport nyait pas. --Jacques Lacan, "L'Etourdit" -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
