Re: [Xen-users] Patching libc for xen

["john maclean" <jayeola@xxxxxxxxx>]

I've grabbed a specs file from BLAG's repositary and have observed the
following after running `occur` within emacs. specs file for glibc.

26 lines matching "xen" in buffer glibc.spec.
    8:%define xenarches i686 athlon
    9:%ifarch %{xenarches}
   10:%define buildxen 1
   11:%define xenpackage 0
   13:%define buildxen 0
   14:%define xenpackage 0
  137:%if %{xenpackage}
  138:%package xen
  139:Summary: The GNU libc libraries (optimized for running under Xen)
  143:%description xen
  145:perform as well under the Xen hypervisor.  This package
provides alternative
  146:library binaries that will be selected instead when running under Xen.
  148:Install glibc-xen if you might run your system under the Xen hypervisor.
  931:%if %{buildxen}
  992:%if %{buildxen}
 1216:%if %{xenpackage}
 1293:%if %{buildxen}
 1511:%if %{xenpackage}
 1512:%post xen -p /sbin/ldconfig
 1513:%postun xen -p /sbin/ldconfig
 1525:%if %{buildxen} && !%{xenpackage}
 1562:%if %{xenpackage}
 1563:%files -f nosegneg.filelist xen
 2230:- put xen libs into the glibc-2*.i686 package instead of a separate one
 2250:- glibc-xen subpackage for i686
 2455:  - double buffer size in getXXbyYY or getXXent on ERANGE

This could mean that I'm good to go if i use the right switch(es)
during the build, right?
