New Security Vulnerabilities channel on Comcast channel 997. Fedora Core 10 was EOLed in 2009...

Upgraded to Fedora 17 "Beefy Miracle" in-place on the same image I've had since Redhat 6.2.  It was a little more challenging than some upgrades due to moving everything into /usr, but overall it's working well.

And the origin of the name is pretty interesting, check it out:

Fedora has always had odd names, but Beefy Miracle ventures into Ubuntu territory...

Could either of you recommend someone associated with the Fedora cvs->git transition that can talk to the Apache folks? There's so much drama going on over there regarding git and their infra people are moving way slow...

Hey look, it's the Fedora Project! On Google+

Check out Fedora 16 if you're into Linux distros. I just finished upgrading the home server last night and it's running smooth. (even if systemctl reminds me way too much of solaris SMF)

Fun fact: I've been upgrading the same system image since Red Hat 6.0. No reinstalls.. and since I never had a CD/dvd all upgrades were via rpm/yum.

You can stop reading now if you don't care about software that keeps the internet from falling over.

Memcached 1.4.10 is now out and this release looks to be the best yet. Check out the release notes and send some kudos over to http://dormando.me/ (Hey Dormando, get on G+ already!)

To do my part I just built the fedora RPMs for f15/f16/rawhide. Try it out on your favorite high-volume server.

Now upgrading Fedora memcached to 1.4.6. I really do like the fedpkg system -- so much better than the old CVS based build system.

It appears that Fedora 12 moved to a new boot init system called dracut.  Sadly due to a number of odd circumstances this has caused me much pain.  Here's my basic config

# dmraid -r 
/dev/sdd: sil, "sil_aiabafajfgba", mirror, ok, 488395120 sectors, data@ 0
/dev/sdc: sil, "sil_aiabafajfgba", mirror, ok, 488395120 sectors, data@ 0

fprintf(stderr, Name ": WARNING %s and %s appear"
" to have very similar superblocks.\n"
" If they are really different, "
"please --zero the superblock on one\n"
" If they are the same or overlap,"
" please remove one from %s.\n",
devices[best[i]].devname, devname,
inargv ? "the list" :
"the\n DEVICE list in mdadm.conf"

Drats! the mirrored fake raid had already mangled my second drive by duplicating the superblock!  Plus since all this was going on in dracut I couldn't fix it.  So I removed the nodmraid option in grub during boot and dug a little deeper. I found that I could keep dracut from doing all this nonsense by adding the following kernel options:

rd_NO_MD rd_NO_DM nodmraid

mdadm --zero-superblock /dev/sdd1

And then rebooting (again!)

# mdadm --manage /dev/md_d0 --add /dev/sdd1

To get rid of the false-positive fake raid setup I found that you can do this with the dmraid tool itself:

[root@mirth ~]# dmraid -E -r /dev/sdd

Do you really want to erase "sil" ondisk metadata on /dev/sdd ? [y/n] :y

[root@mirth ~]# dmraid -E -r /dev/sdc

Do you really want to erase "sil" ondisk metadata on /dev/sdc ? [y/n] :y
