Hi folks,
In both sets of grep's instructions we use the '--with-included-regex'
to prevent grep from using potentially buggy regex code from glibc. Now,
I can understand this in chapter 5 where the host's glibc can't be
guaranteed to work. However, in chapter 6 we have a known version of
glibc. The question is, does anyone know whether recent versions of
glibc still have the buggy regex code, and how can we test/verify it (is
running grep's own testsuite enough to spot any problems)? The reason
I ask is that Jakub Jelinek has done some work on the regex code in
glibc, so I'm wondering if it's still problematic.
For what it's worth I stopped using that option with grep in the chroot pass about a
month ago and it hasn't caused any problems I'm aware of. I still use it when
building the tools
Secondly, following Ken's observation that hotplug's Makefile creates
the /var/log/hotplug directory I removed that instruction from the book.
That just leaves us touching a file at /var/log/hotplug/errors. I
can't believe that hotplug doesn't create this file itself, if it
doesn't already exist. Can anyone (Jim!) confirm that this instruction
is really necessary?
Living without it doesn't cause me any problems
