How to do a clean reinstall of initramfs

I was getting the error mentioned in this post on ubuntu 10.04. I upgraded to ubunu 10.10 through software update and again I'm getting this error.

mount: mounts none on /dev/pts failed: Device

Here is the boot log:

IP-Config: no response after 4 secs - giving up
/scripts/init-premount/dropbear: line 32: ipconfig: not found
/scripts/init-premount/dropbear: line 32: ipconfig: not found

/scripts/init-premount/dropbear: .: line 32: can't open '/tmp/net-*.conf'
fsck from util-linux-ng 2.17.2

I had purged dropbear, and it looks like some scripts are still remaining. Is it possible to do a clean re-install of initramfs?

EDIT 1: sudo update-initramfs -u doesn't solve the issue. Also sudo update-initramfs -c -k all also doesn't solve the issue.

From ubuntu nixnotwin

• sudo update-initramfs -u
  

  Simple as. Shouldn't be able to hurt anything.

  On another note, you should ask whoever packages dropbear to add that to their postrm script.

  From Oli

• I was able to solve the dropbear issue.

  I did the following:

  1. I removed all dropbear related files by using the command: sudo find / -name dropbear* -exec rm -ri {} \;
  2. Then I did sudo update-initramfs -c -k all
  3. Now only this error remains mount: mounts none on /dev/pts failed: Device It looks like there is an obsolete mount entry created by dropbear in the config files which get executed in pre-init stages. If some one could figure out that config file, I would be able to solve the whole issue.
  hhlp : do you check your /etc/fstab ?

  nixnotwin : Yes I did. There is no entry for /dev/pts in fstab.
