I downloaded the Fedora-17-arm-console.tar.xz rootfs and put it on my
sheevaplug. Everything was fine except named wouldn't start, was
getting a timeout error from systemd.

i.e

Jun 30 11:52:54 tau systemd[1]: PID file /run/named/named.pid not readable (yet?) after start.
Jun 30 11:53:19 tau systemd[1]: named.service operation timed out. Terminating.
Jun 30 11:53:19 tau systemd[1]: Unit named.service entered failed state.

Turns out that the problem was due to /var/run being a directory and
not a symlink to /run (as in F16) i.e

from the rootfs tar

drwxr-xr-x root/root         0 2012-06-18 02:32 var/run/
drwxr-xr-x root/root         0 2012-04-30 15:12 var/run/NetworkManager/
-rw-rw-r-- root/utmp         0 2012-06-17 21:56 var/run/utmp
drwxr-xr-x root/root         0 2012-05-02 10:38 var/run/wpa_supplicant/
drwxr-xr-x root/root         0 2012-02-09 01:25 var/run/sepermit/
drwxr-xr-x root/root         0 2012-02-09 01:25 var/run/faillock/
drwxr-xr-x root/root         0 2012-02-09 01:24 var/run/console/
drwxr-xr-x root/root         0 2012-02-02 17:03 var/run/ppp/
drwxr-xr-x root/root         0 2012-05-02 09:02 var/run/setrans/
drwxrwxr-x root/root         0 2012-03-23 19:31 var/run/netreport/

And named was putting its pid file under /var/run/named/named.pid and
systemd was looking for it in /run/named/named.pid

Once I moved all the /var/run stuff to /run and made /var/run a symlink
ro /run, i.e

lrwxrwxrwx. 1 root root 6 Nov 20  2011 /var/run -> ../run

named now starts fine under systemd.

Also, (a minor thing) /run is a tmpfs mount, i.e

tmpfs on /run type tmpfs (rw,nosuid,nodev,mode=755)

so having the following in the rootfs

drwxr-xr-x root/root         0 2012-02-29 23:18 run/blkid/
drwxr-xr-x root/root         0 2012-02-29 23:19 run/mount/
-rw-r--r-- root/root         0 2012-02-29 23:19 run/mount/utab
drwxr-xr-x root/root         0 2012-02-11 05:46 run/lock/
drwxr-xr-x root/root         0 2012-02-02 17:03 run/lock/ppp/

isn't much use.

Cheers,
Andrew
