-Subject: [PATCH] Don't auto-enable ACCT_TOOLS_SETUID if PAM is detected
-
-Here's a sad story:
-
-* 70971457 is merged into shadow, allowing newgidmap/newuidmap to be
-installed with file caps rather than setuid.
-* https://bugs.archlinux.org/task/63248 is filed to take advantage of
-this.
-* The arch maintainer of the 'shadow' package notices that this doesn't
-work, and submits a pull request to fix this in shadow.
-* edf7547ad5 is merged, fixing the post install hooks.
-
-The problem here is that distros have been building shadow with PAM for
-O(years), but the install hooks have silently failed due to the
-combination of the directory mismatch (suidubins vs suidsbins) and later
-success with setuid'ing newgidmap/newuidmap.
-
-With the install hooks fixed, those of us (Arch[1] and Gentoo[2] so far)
-who never built shadow explicitly with --enable-account-tools-setuid are
-now getting setuid account tools, and don't have PAM configuration
-suitable for use with setuid account management tools.
-
-It's entirely unclear to me why you'd want this, but I assume there's
-some reason out there for it existing. Regardless, setuid binaries are
-dangerous and shouldn't be enabled by default without good reason.
