[Touch-packages] [Bug 1890520] Re: catastrophic bug with deluser command -- destroys large number of system files
Notice also there is a serious transparency problem. The output only shows files for which removal failed. This acutely heightens the destruction because it potentially destroyed *thousands* of files as I sat there and let it run. The tool gives no idea how what's being destroyed. The admin has to trust that their understanding of the scope of removal is accurate. In the absence of errors, an admin would let it run through to the end, resulting in maximum damage. This tool badly needs a --simulate option. And regardless of simulation, it should show what files are affected. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to adduser in Ubuntu. https://bugs.launchpad.net/bugs/1890520 Title: catastrophic bug with deluser command -- destroys large number of system files Status in adduser package in Ubuntu: New Bug description: I installed rygel and created a specific rygel user to run it with (as directed by the docs).
