'nix-daemon' now creates subdirectories for users when they first
connect.
Fixes#509 (CVE-2019-17365).
Should also fix#3127.
(cherry picked from commit 5a303093dcae1e5ce9212616ef18f2ca51020b0d)
When we are in single user mode, we still want to have access to
profiles. This way things in Nixpkgs that rely on them getting set
accurately are done in both cases. The point where I hit this is with
using aspell which looks in NIX_PROFILES:
https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/aspell/default.nix
Before this patch, NIX_PROFILES was never set in single user mode!
This corrects that.
Checking for MANPATH without quotes always returns true, so that it breaks bash-completion for man pages on modern systems without MANPATH environment variable.
Currently, man has issues finding man pages for Nix-installed
application (also, `nix-env --help` doesn't work). The issue is caused
by custom `$MANPATH` set by my system. That makes man use it instead of
searching in default location.
Either of next lines workaround the issue:
```sh
unset MANPATH
export MANPATH=$HOME/.nix-profile/share/man:$MANPATH
```
This patch adds the later line to the `nix-profile.sh` if user has
`MANPATH` set. (Not clearing `MANPATH` as that would be disrespect of
user's preferences.)
As a side-effect, host's man might find man pages installed by Nix.
This reverts commit 76f985b92d. We
shouldn't mess with $MANPATH, because on some "man" implementations
(like NixOS'), the default value on $MANPATH is derived from $PATH. So
if you set $MANPATH, you lose the default locations.
Commit 6a214f3e06 copied most of the Nix
shell initialisation code from NixOS to nix-profile.sh; however, that
code assumes a multi-user install and is Linux-specific (e.g. it calls
the "stat" command). So go back to the simple single-user version.
Fixes#49.
Commit 6a214f3e06 reused the NixOS
environment initialisation for nix-profile.sh, but this is
inappropriate on systems that don't have multi-user support enabled.

$prefix/var/nix/links is gone. Profiles can be stored anywhere.
* The current profile is now referenced from ~/.nix-profile, not

* The roots to the garbage collector now have extension `.gcroot', not
`.id'.
the symlink ~/.nix-userenv to the given argument (which defaults to
.../links/current). /etc/profile.d/nix-profile creates this symlink
if it doesn't exist yet. Example use:
$ nix-env -l my_profile -i foo.nix subversion quake
$ nix-env -p my_profile
I don't like the term "profile". Let's deprecate it :-)
dynamically links against libdb4 (?!), due to LD_LIBRARY_PATH it picks
up our libdb4 instead of SuSE's libdb4, but our libdb4 uses another
glibc so loading barfs.
Instead, all packages should use rpaths to store library locations in
executables/libraries. The disadvantage is that overriding rpaths is
harder. (It is possible by invoking the dynamic linker directly, e.g.,
`/lib/ld-linux.so.2 --ignore-path LIST program args...' to ignore the
rpath for the libraries in LIST). It would be better to use DT_RUNPATH,
which is consulted by the dynamic linker *after* LD_LIBRARY_PATH but
*before* ld.so.cache and the system directories.
