[Ltib] Ubuntu 12.04 vs 10.04 libc.so libpthread.so absolute path removal

[Sale, Devin M]

Hi,

In the base_libs.spec there's this little bit of perl code.

# remove absolute paths from text search files (if they exist)
perl -w -e '
    @ARGV = grep { `file $_` =~ m,ASCII C program text, } @ARGV;
    exit(0) unless @ARGV;
    $^I = ".bak";
    while(<>) {
        s,[\S/]+/,,g if m,^GROUP,;
        print;
    }
    ' $RPM_BUILD_ROOT/%{pfx}/lib/libc.so \
      $RPM_BUILD_ROOT/%{pfx}/lib/libpthread.so \
      $RPM_BUILD_ROOT/%{pfx}/usr/lib/libc.so \
      $RPM_BUILD_ROOT/%{pfx}/usr/lib/libpthread.so

which does what the comment says and leaves a libc.so.bak and lipthread.so.bak 
in the rootfs.

When moving LTIB from Ubuntu 10.04 to 12.04 the *.bak files go away because the 
file utility changed like this:
On 10.04:
address@hidden:~$ file libc.so.bak
libc.so.bak: ASCII C program text

On 12.04:
dzq92s:~$ file libc.so
libc.so: ASCII English text


Why remove the absolute paths?

What is the ramification of not doing this?

Should the *.bak files be left in the rootfs?

Regards,
Devin
