Debian etch to lenny upgrade

I've just upgraded Debian etch to lenny and so far only had a few issues.

• There were two root users in mysql, one without password, I removed the one with no password
• updatedb and locate no longer exist on system even if findutils exists, you need to install package mlocate
• php can no longer access mysql - Fatal error: Call to undefined function: mysql_connect(), you need to install php5-mysql which upgrades you to php5

OUTSTANDING ISSUES (I have not had time to fix)

• ejabber: pyMSNt no longer working
• Anything I've missed ?
