Hello, please, consider the following output of part of mine /etc/passwd:

These 'users' are not allowed to login: either '/bin/false' or '/sbin/nologin' is used as login shell (another question raises: why two variants? why not just '/bin/false' or '/sbin/nologin'?) but they home directoriy is '/'. I wonder why '/' was chosen for that? Is it possible to change home directories for these 'users' to, say, '/dev/null' or '/nonexistent'?
The origin of my question comes from use of 'davfs': when used by normal user (being member of 'network' group) 'mount.davfs' refuse mounting to '/mnt/webdav' because '/' is home directory for some users. I found this 'workaround': http://www.gentoo-wiki.info/WebDAV (sec. "Troubleshooting") so manually changed the home directories for these users to '/dev/null' (I'm not sure is it save or good way).
I don't think it would be any problem to use /dev/null or anything else in there, but it was probably the easiest thing to do (because nobody bothers with writing weird home directory names for those users.
