14<listitem><para><userinput>--disable-perl-regexp</userinput>: This makes sure
15that grep does not get linked against a PCRE library that may be present on
16the host, but would not be available once we enter the chroot environment.</para></listitem>
17<listitem><para><userinput>--with-included-regex</userinput>: This ensures that
18grep uses it's internal regular expression code. Without it, it will use
19the code from glibc, which is known to be slightly buggy.</para></listitem>
