</div>Don't get too too comfortable. I don't know if Ubuntu is transitioning<br>
to systemd yet or not (or planning to or creating a new alternative) but<br>
this was a talk tease from a talk delivered by my friend and co-guru<br>
Mark Torres (formerly of Suse fame) to the Atlanta Unix Users Group a<br>
couple of months ago...<br>
<br>
--<br>
Marc will be discussing some of the myths, uses and advantages of<br>
this replacement of the Linux sysvinit package. Despite the best<br>
efforts of many (and a never ending supply of mailing list<br>
flames, holy water, silver bullets, wooden stakes, poisons and<br>
evil looks) it is coming soon to a Linux Distro near you.<br>
--<br>
<br>
You may have to deal with the likes of systemd sooner or later (or some<br>
other variant in similar concept). This is not something peculiar to<br>
Fedora (OpenSuse, and Arch Linux both have systemd as will RHEL, CentOS,<br>
Scientific Linux, etc...). By the time it gets to Ubuntu, though, I<br>
suspect it will be much more stable.<br>
<br>
Seems like Fedora adopted it early (very much like Ubuntu with Unity)<br>
and Fedora has sort of been the proving ground for systemd (that's what<br>
Fedora is for). Personally, I'm in the "holy water and wooden stakes"<br>
category (and I have at least one flame war on the systemd list to back<br>
me up) with regards to systemd but it is what it is. We've been dealing<br>
with it as it evolves.<br>
<br>
It's worth noting that I've decided that I will never get Fedora 15 or<br>
Fedora 16 running in a container (they will work as a host, however) due<br>
to incompatible versions of systemd. But F15 and F16 are EOL and thus<br>
not worth any effort or stress. They (systemd) obviously found<br>
solutions for the havoc they caused in those versions and we have<br>
managed to get F17 and F18 working with the recent versions of systemd.<br>
It's not Fedora, it's systemd that create these problems.<br>
<br>
OTOH... Unity caused me to totally abandon Ubuntu. It totally broke<br>
freenx and the NX support and try as I might, I could not get it to work<br>
after trying for 2 or 3 releases of Ubuntu. Even though the freenx<br>
package was still in the repos, several of the libraries upon which it<br>
depended were gone or deprecated. I tried all the manual patches and<br>
source compiles and nothing worked or created irreconcilable conflicts.<br>
If I can't use NX to get graphic desktops in a container or on a remote<br>
host system, Ubuntu became useless to me and I had to rip it out where I<br>
had it. Even the laptops for my grandkids (which were running Ubuntu)<br>
are now running on Fedora for that reason (so grandpa can have a remote<br>
desktop on their laptop and do remote graphical administration).<br>
<br>
Maybe they have since fixed it but they already lost me on that one<br>
point alone. I do need to get some (at least one) containers running<br>
Ubuntu running just so I can run Oregano (Electronics Schematic CAD<br>
program with simulation capabilities) which I can not get to work on<br>
Fedora 18 (Fedora 19 might work) due to some gtk3+ library issues. So<br>
maybe I'll revisit Ubuntu again soon. I have successfully built an<br>
Ubuntu container on a Fedora host. That's one of the nice things, that<br>
I can cross build Ubuntu on a Fedora host. I think (but I haven't<br>
tried) the reverse is true. If not, I may have to fix that in the<br>
Fedora template. That's not true of many of the other templates. I<br>
can't build an Arch Linux container on a Fedora host. That's something<br>
the container owners have to address.<br>
<br>
We've gotten it (systemd) working and functional (maybe not totally<br>
"pretty") and now it's more a matter of getting the updated revs into<br>
the downstream releases to make it just as easy. That's the way it<br>
works. All the template maintainers (and I'm just a contributor) are<br>
shooting at moving targets. What's in the git repo right now for the<br>
Fedora template is pretty sweet (if I do say so myself) and will build<br>
Fedora containers out of the box.<br>
<br>
Which reminds me. The dudes that do the Fedora Remix for the Raspberry<br>
Pi just renamed their distribution to Pidor (shades of Kubuntu, Edubuntu<br>
and the other remixes of Ubuntu). That's going to break the lxc-fedora<br>
template on the Raspberry Pi (yet again - pounding head on desk). Right<br>
now, AFAICT, the ARM support for Ubuntu is only for ARM7 and up which<br>
leaves out the RPi (ARM6). Oh well. It never ends.<br>
