Subject: [ptxdist] [PATCH] glibc: install ldconfig and create ld.so.cache
Date: Wed, 7 Sep 2016 23:40:03 +0200 [thread overview]
Message-ID: <20160907214003.7711-1-clemens.gruber@pqgruber.com> (raw)
Add an option to install the ldconfig binary from the toolchain and
another one to enable the generation of /etc/ld.so.cache at first boot
with a rc-once.d script.
Use only the new format, which is supported since glibc 2.2 from the
year 2000.
