+Subject: [PATCH] update-ca-certificates: use relative symlinks from
+ $ETCCERTSDIR
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+update-ca-certificates symlinks (trusted) certificates
+from $CERTSDIR or $LOCALCERTSDIR into $ETCCERTSDIR.
+update-ca-certificates can call hook scripts installed
+into /etc/ca-certificates/update.d. Those scripts are
+passed the pem file in /etc/ssl/certs/ that was added or
+removed in this run and those pem files are absolute
+symlinks into $CERTSDIR or $LOCALCERTSDIR at the moment.
+
+When running update-ca-certificates during image build
+time, they thusly all point into the host's file system,
+not into the $SYSROOT. This means:
+* the host's file system layout must match the one
+  produced by OE, and
+* it also means that the host must have installed the same
+  (or more) certificates as the target in $CERTSDIR and
+  $LOCALCERTSDIR
+
+This is a problem when wanting to execute hook scripts,
+because they all need to be taught about $SYSROOT, and
+behave differently depending on whether they're called
+at image build time, or on the target, as otherwise they
+will be trying to actually read the host's certificates
+from $CERTSDIR or $LOCALCERTSDIR.
+
+This also is a problem when running anything else during
+image build time that depends on the trusted CA
+certificates.
+
+Changing the symlink to be relative solves all of these
+problems. Do so.
+
