Minor patch, but useful to me at least. I really find it convenient to have a symbolic link to the latest xen kernel I''ve built/installed for testing purposes. When the kernel went from 2.6.9 -> 2.6.10 recently, I hit all kind of strange problems until I realized that I was booting the new xen stuff with an old kernel. This might also come in handy if someone were inclined to make install.sh smarter so that it modifies grub. The patch was made against xen-2.0-testing but should apply ok to all the trees. -- Thanks, Paul Larson plars@linuxtestproject.org http://www.linuxtestproject.org diff -Nru a/buildconfigs/mk.linux-2.6-xen0 b/buildconfigs/mk.linux-2.6-xen0 --- a/buildconfigs/mk.linux-2.6-xen0 2005-01-20 15:48:20 -06:00 +++ b/buildconfigs/mk.linux-2.6-xen0 2005-01-20 15:48:20 -06:00 @@ -18,6 +18,8 @@ $(MAKE) -C $(LINUX_DIR) ARCH=xen INSTALL_MOD_PATH=$(INSTALL_DIR) modules_install ; \ fi $(MAKE) -C $(LINUX_DIR) ARCH=xen INSTALL_PATH=$(INSTALL_DIR) install + ln -s /boot/vmlinuz-$(FULLVERSION) \ + $(INSTALL_DIR)/boot/vmlinuz-$(EXTRAVERSION) $(LINUX_DIR)/include/linux/autoconf.h: pristine-linux-$(LINUX_VER) rm -rf $(LINUX_DIR) diff -Nru a/buildconfigs/mk.linux-2.6-xenU b/buildconfigs/mk.linux-2.6-xenU --- a/buildconfigs/mk.linux-2.6-xenU 2005-01-20 15:48:20 -06:00 +++ b/buildconfigs/mk.linux-2.6-xenU 2005-01-20 15:48:20 -06:00 @@ -18,6 +18,8 @@ $(MAKE) -C $(LINUX_DIR) ARCH=xen INSTALL_MOD_PATH=$(INSTALL_DIR) modules_install ; \ fi $(MAKE) -C $(LINUX_DIR) ARCH=xen INSTALL_PATH=$(INSTALL_DIR) install + ln -s /boot/vmlinuz-$(FULLVERSION) \ + $(INSTALL_DIR)/boot/vmlinuz-$(EXTRAVERSION) $(LINUX_DIR)/include/linux/autoconf.h: pristine-linux-$(LINUX_VER) rm -rf $(LINUX_DIR)

[Xen-devel] [PATCH] (revised slightly) create kernel symlinks in /boot

The cp -dR in make install-kernels should ensure that the link is preserved, and cp -fdr likewise in install.sh. -- Thanks, Paul Larson plars@linuxtestproject.org http://www.linuxtestproject.org diff -Nru a/buildconfigs/mk.linux-2.6-xen0 b/buildconfigs/mk.linux-2.6-xen0 --- a/buildconfigs/mk.linux-2.6-xen0 2005-01-21 10:19:56 -06:00 +++ b/buildconfigs/mk.linux-2.6-xen0 2005-01-21 10:19:56 -06:00 @@ -18,6 +18,8 @@ $(MAKE) -C $(LINUX_DIR) ARCH=xen INSTALL_MOD_PATH=$(INSTALL_DIR) modules_install ; \ fi $(MAKE) -C $(LINUX_DIR) ARCH=xen INSTALL_PATH=$(INSTALL_DIR) install + ln /boot/vmlinuz-$(FULLVERSION) \ + $(INSTALL_DIR)/boot/vmlinuz-$(EXTRAVERSION) $(LINUX_DIR)/include/linux/autoconf.h: pristine-linux-$(LINUX_VER) rm -rf $(LINUX_DIR) diff -Nru a/buildconfigs/mk.linux-2.6-xenU b/buildconfigs/mk.linux-2.6-xenU --- a/buildconfigs/mk.linux-2.6-xenU 2005-01-21 10:19:56 -06:00 +++ b/buildconfigs/mk.linux-2.6-xenU 2005-01-21 10:19:56 -06:00 @@ -18,6 +18,8 @@ $(MAKE) -C $(LINUX_DIR) ARCH=xen INSTALL_MOD_PATH=$(INSTALL_DIR) modules_install ; \ fi $(MAKE) -C $(LINUX_DIR) ARCH=xen INSTALL_PATH=$(INSTALL_DIR) install + ln /boot/vmlinuz-$(FULLVERSION) \ + $(INSTALL_DIR)/boot/vmlinuz-$(EXTRAVERSION) $(LINUX_DIR)/include/linux/autoconf.h: pristine-linux-$(LINUX_VER) rm -rf $(LINUX_DIR)
