As of right NOW, Ubuntu uses a "different" way of booting.
*IF* /var/run and /var/lock are NOT on the initial root (/) filesystem
before the other filesystems are mounted then it fails to boot properly.
In fact "/etc/init.d/mountvirtfs" executed early (S01) in the boot
process has the initial mounting of the tmpfs stuff in it here it is:
# Mount standard /proc filesystem
TYPE=
case "$KERNEL" in
Linux|GNU)
TYPE=proc
;;
*FreeBSD)
TYPE=linprocfs
;;
*)
TYPE=procfs
;;
esac
# Mount standard /proc and /sys.
domount $TYPE /proc
domount sysfs /sys
# Mount /var/run and /var/lock as tmpfs.
# /var may be on another drive so create /var/run if we need to
domount tmpfs /var/run "-o mode=0755"
domount tmpfs /var/lock "-o mode=1777"
# Mount /proc/bus/usb -- though all software should be modified to
# use /dev/bus/usb instead now
domount usbfs /proc/bus/usb
Then later in the boot process, it "remounts" the dirs to a "safe
location" for saving later... then once /var is properly mounted it
remounts them where they properly need to be. Done in mtab (S22) then in
mountall (S35)
I KNOW this is the way it is in Ubuntu, I had a server I setup for a
customer. After I did initial setup, I had to add a real Raid Array
(2.2TB) to various filesystems of which one was /var (before /var was on
root). During the re-deploy I missed making the /var/run and /var/lock
directories as *I* would NEVER have done that normally. This caused
failing to reboot properly, not bringing up the NICs and periodically
falling off the network as well.
I "got" to make a 2 hour each way and 3-5 hour troubleshooting "Gratis"
travel call each time this thing failed. (4 times)
It was tracked down to there NOT being /var/run and /var/lock on the
root(/) filesystem
So, please DO NOT tell me what NOT to do. I specified this was on Ubuntu
on the off chance the person was using Ubuntu.
I'll bet the Lenny (Etch+1) has this.
