Automatic creation of last-known-good boot configuration
On Debian testing I've been bitten by the systemd upgrade and the systemd package split recently, rendering my dracut-LUKS-based system unbootable. I know that my warranty is void since I'm on testing, but both these issues would have been much easier to cope with if there had been some good backup of my initramfs and kernel below /boot. So I thought that there might be some automatism like this: If the currently used kernel and initramfs have been in use already N times and if the boot time has been lower then M minutes each time (and if some other conditions are fulfilled), then consider that kernel and initramfs good and save them away where they will not be overwritten by regular kernel/initramfs maintenance. Scripting something like that shouldn't be too hard, but I wonder if there already is a package implementing that? A cursory search hasn't brought up anything. There is package dracut-config-rescue, but that only configures a variable that does not seem to be used by dracut itself. Please CC me when replying. Thanks!
Debian Jessie: Issue with Samba 4 as PDC with NTPd and Windows 7 clients
Hello there, debian is the best - when it works :-) Maybe someone of you will have an idea. I've run into an issue with time synchronisation on windows 7 clients in a samba 4 ad domain. Setup is as follows: Server is running debian jessie with samba 4 as PDC and NTPd. I followed the tutorial at https://wiki.samba.org/index.php/Time_Synchronisation to the letter. File sharing, user logins etc. works great. And time snychronisation does work between the PDC and other servers and unix clients. But time synchronisation does NOT work with windows 7 clients (w32tm). I checked with tcpdump, the windows client is sending a message but the server nerver responds to the windows client. Other request are handled fine. However, if i start NTPd as root, now the windows clients do get a response back. I assumed a permission problem with the signd socket. However it is setup as requested by the tutorial to: drwxr-x---+ 2 root ntp 4096 Dec 6 19:47 ntp_signd and the socket itself to: srwxr-xr-x 1 root root 0 Dec 6 19:47 socket For tests changing the permissions on ntp_signd 777 does not work. Only starting the ntpd as root produces answers to the windows clients. This seems wrong to me. Any ideas on how to fix this would be greatly appreciated. Cheers Jens
