Could I write it in perl? $ file /var/lib/dpkg/info/*.preinst|grep -v "shell script text" Yes preinst scripts can be in perl - the other alternative is a compiled executable but that is only really an option if the package itself is already Arch:any. So, your packge is left with perl if shell isn't practical. I don't know the package but sometimes it is only necessary to identify that the upgrade needs to be run in the preinst and then actually handle the workload in the postinst (when you could use python), maybe via a dpkg trigger. What portion of the *results* of the parsing is actually required for the configuration of calendarserver itself? It is worth investigating whether a preinst is actually required or whether the work can be postponed. > Also is there any estimate date on the release of squeeze? When the RC bugs are fixed. It seems unlikely that this particular package would affect the release as the new version won't migrate into testing now anyway - the broken preinst / Pre-Depends-not-discussed-previously-on-devel issue only exists in unstable and that can be fixed without affecting the release of Squeeze. (It does need to be fixed though.) -- Neil Williams ============= http://www.linux.codehelp.co.uk/
