This is a flag that disables subversion keyword substitution.
Keyword substitution inserts metadata into the files being checked
out, and is therefore somewhat at odds with build reproducibility.
In particular, it can become a problem if you're trying to switch
between svn and a git export of the same thing (keyword substitutions
are normally not exported into git).
There are some SVN repositories out there which don't have revision information
tied to externals. By using ignoreExternals, fetchsvn won't fetch these
externals anymore, so the fetch won't fail with a checksum mismatch, should
there be some changes in some of those external repositories.

server's certificate. This is perfectly safe: we don't care whether
the server is being spoofed --- only the cryptographic hash of the
output matters.

the tree being fetched from a Subversion repository. The revision
number is now optional (and defaults to HEAD).
This makes `fetchsvn' more pure. First, a URL/revision tuple does
not uniquely identify a file resource, since the repository itself
might change. Second, `svn:external' attributes can cause arbitrary
resources to be exported.
A script `nix-prefetch-svn' has been provided to determine the hash
of a URL.

* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.
