From 9397cd30c8a6ffd65fc3b85985ea59ecfb72672b Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Sat, 27 Oct 2007 00:46:59 +0000 Subject: * Support for doing builds in a chroot under Linux. The builder is executed in a chroot that contains just the Nix store, the temporary build directory, and a configurable set of additional directories (/dev and /proc by default). This allows a bit more purity enforcement: hidden build-time dependencies on directories such as /usr or /nix/var/nix/profiles are no longer possible. As an added benefit, accidental network downloads (cf. NIXPKGS-52) are prevented as well (because files such as /etc/resolv.conf are not available in the chroot). However the usefulness of chroots is diminished by the fact that many builders depend on /bin/sh, so you need /bin in the list of additional directories. (And then on non-NixOS you need /lib as well...) --- src/libutil/util.hh | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'src/libutil/util.hh') diff --git a/src/libutil/util.hh b/src/libutil/util.hh index f72a6f82011b..0ed98118c53b 100644 --- a/src/libutil/util.hh +++ b/src/libutil/util.hh @@ -72,8 +72,9 @@ void makePathReadOnly(const Path & path); /* Create a temporary directory. */ Path createTempDir(const Path & tmpRoot = ""); -/* Create a directory and all its parents, if necessary. */ -void createDirs(const Path & path); +/* Create a directory and all its parents, if necessary.
