Merge pull request #3445 from gnprice/pr-installer-colors
installer: Fix terminal colors.

Greg Price 7313aa267b installer: Fix terminal colors.
The install-multi-user script uses blue, green, and red colors, as
well as bold and underline, to add helpful formatting that helps
structure its rather voluminous output.

Unfortunately, the terminal escape sequences it uses are not quite
well-formed.  The relevant information is all there, just obscured
by some extra noise, a leading parameter `38`.  Empirically, the
result is:

 * On macOS, in both Terminal.app and iTerm2, the spurious `38` is
   ignored, the rest of the escape sequence is applied, and the colors
   show up as intended.

 * On Linux, in at least gnome-terminal and xterm, the spurious `38`
   and the next parameter after it are ignored, and what's left is
   applied.  So in the sequence `38;4;32`, the 4 (underline) is
   ignored but the 32 (green) takes effect; in a more typical sequence
   like `38;34`, the 34 (blue) is ignored and nothing happens.

These codes are all unchanged since this script's origins as a
Darwin-only script -- so the fact that they work fine in common macOS
terminals goes some way to explain how the bug arose.

Happily, we can make the colors work as intended by just deleting the
extra `38;`.  Tested in all four terminals mentioned above; the new
codes work correctly on all of them, and on the two macOS terminals
they work exactly the same as before.

---

In a bit more technical detail -- perhaps more than anyone, me
included, ever wanted to know, but now that I've gone and learned it
I'll write it down anyway :) -- here's what's happening in these codes:

An ECMA-48 "control sequence" begins with `\033[` aka "CSI", contains
any number of parameters as semicolon-separated decimal numbers (plus
sometimes other wrinkles), and ends with a byte from 0x40..0x7e.  In
our case, with `m` aka "SGR", "Select Graphic Rendition".

An SGR control sequence `\033[...m` sets colors, fonts, text styles,
etc.  In particular a parameter `31` means red, `32` green, `34` blue,
`4` underline, and `0` means reset to normal.  Those are all we use.

There is also a `38`.  This is used for setting colors too... but it
needs arguments.  `38;5;nn` is color nn from a 256-color palette, and
`38;2;rr;gg;bb` has the given RGB values.

There is no meaning defined for `38;1` or `38;34` etc.  On seeing a
parameter `38` followed by an unrecognized argument for it, apparently
some implementations (as seen on macOS) discard only the `38` and
others (as seen on Linux) discard the argument too before resuming.

Greg Price e40e01c1dd doc: Files in the store have modes 444/555, not 644/755
This line has been this way since it was written, in 9e08f5efe
in 2006.

I think it was just a small mistake then; Eelco's thesis earlier
that year says the permission on each file is set to 0444 or 0555
in a derivation's output as part of the build process.  In any
case I'm pretty sure that's the behavior now.

Greg Price 26851dd2c2 installer: Set files read-only when copying into store
After installing Nix, I found that all the files and directories
initially copied into the store were writable, with mode 644 or 755:

  drwxr-xr-x 9 root root 4096 Dec 31  1969 /nix/store/ddmmzn4ggz1f66lwxjy64n89864yj9w9-nix-2.3.3

The reason is that that's how they were in the unpacked tarball, and
the install-multi-user script used `rsync -p` without doing anything
else to affect the permissions.

The plain `install` script for a single-user install takes care to
do a `chmod -R a-w` on each store path copied.  We could do the same
here with one more command; or we can pass `--chmod` to rsync, to
have it write the files with the desired modes in the first place.

Tested the new `rsync` command on both a Linux machine with a
reasonably-modern rsync (3.1.3) and a Mac with its default, ancient,
rsync 2.6.9, and it works as expected on both.  Thankfully the latter
is just new enough to have `--chmod`, which dates to rsync 2.6.7.

sandbox: fix /bin/sh on catalina
Sadly 10.15 changed /bin/sh to a shim which executes bash, this means it
can't be used anymore without also opening up the sandbox to allow bash.

    Failed to exec /bin/bash as variant for /bin/sh (1: Operation not permitted).
