[gentoo-user] systemd how can I get a service to start after network is up
Hi. I have a simple, static, ethernet network. However when booting
using systemd, a number of services which should start only after the
network is up, insist on starting in parallell and so fail for various
reasons. Here is my network service and my ntpdate service file, and I
would like to know how to get the ntpdate service file to wait till the
network is up before trying to start.
Thanks in advance for any suggestions.

[gentoo-user] Use Flags and Updating
Hi all. How do I get Portage to update all software to use my new USE flags? I made some modifications to the variable, and I want to make sure that all packages can use the flags.

Hi, you can use the --newuse option of emerge, like this: # emerge --newuse world you should also take a look at --changed-use. This ignores irrelevant changes since installation. ~frukto

Hi there,
setting After=network.target should just work (tm). I have a few
custom service files which need a working network connection, and using
this setting words for me.
systemd-analyze plot boot.svg also shows the these services only start
after the network is up.

This looks fine. GRUB_DEFAULT=kernel-3.14.4-gentoo GRUB_HIDDEN_TIMEOUT=3 GRUB_TIMEOUT=10 GRUB_GFXMODE=1024x768 GRUB_DISABLE_RECOVERY=true This also looks fine I need ideas as where to look, what to fix to get a newer kernel booting from grub2. Not any changes since 3.13 series was first used: (3.13.1) Note this problem started with kernel 3.13.7-gentoo and has persisted through 3.14.4. I have even diff the .config files [1] For anyone to give you a useful answer, we would need more detailed information about your specific issue - for example: - - how far through the boot process does the broken kernel get? - - Are there any error messages or stack traces? - - Is there any display at all? - - What is the kernel cmdline used to boot the kernel? - - Do you use an initramfs? It never tries to boot. Grub just sits there withe phrase (did not copy it down) where it says what version it will boot on the screen please do copy the phrase to this list, I would be interested to know and it does nothing (locked up?) I have to cntlaltdel or push from the grub2 menu can you choose your old kernels and boot them? is it sitting waiting for you to press enter but perhaps there is a wierd usb-legacy thing in the bios preventing the keyboard working ? does it appear to acknowledge the pressing of enter by not making you wait for the timeout and then just goes to a blank screen ? a flashing cursor ? a manual reset. It never tries to load the kernel. Does not matter if I try a 3.13.7 or 3.14.x, I've rebuilt them quite a few times and did all the grub2 steps, but none of the newer kernels will boot. what about # cat /etc/portage/make.conf # gcc-config -l # uname -a # ls -lah /usr/src/linux/arch/x86_64/boot/bzImage I was thinking maybe that you have made another change somewhere that is making the compilation of a new kernel skewiff... i.e. it's your compiler (build environment) not your grub that might be at fault Nothing was done to the bios. The only change was to get rid of ATI Frame buffer support as suggested upon a recent update: * Checking for suitable kernel configuration options... * CONFIG_FB_RADEON:should not be set. But it is. * Please check to make sure these options are set correctly. * Failure to do so may cause unexpected problems. again stupid question but have you tried compiling with this option back in ? i.e. could it be somehow silently booting but not updating the screen (clutching at straws i know) James
