Yes, the difference between 'su' and 'su -' (aka 'su -l') is to preserve environment or not. Generally preserving the environment of a different user when switching is a really bad idea, so basically you always want to do 'su -'. You are correct though that the old (src:shadow) su would, even when preserving environment, still alter it slightly. The PATH and IFS environment variables where apparently always alterened even when you specified 'preserve environment'. Since I guess the difference between using 'su' and 'su -' is something we'll keep repeating and teaching people for all eternity the difference in behaviour is quite user visible and unfortunate. I'll make sure to document it in the NEWS file atleast. (FYI https://salsa.debian.org/debian/util-linux/commit/ce2bd4bd05f11af1b85ce8f5c4e52807671122ed ) If you notice any other differences, please report back so they can be written down as well. (Merge requests even more welcome!) > > > Feel free to close this bug, sorry for the noise. As a bug submitter you're fully entitled to do so yourself and as you already seems to be aware of just sending a mail to -done is enough. Regards, Andreas Henriksson
