Comment 13 for bug 302870

Updated patch attached.

This patch introduces two changes based on Martin's feedback...
 1) drops ecryptfs-utils from a Recommends to a Suggests
 2) moves the &which() call to the parameter sanity checking section, such that calling adduser --encrypt-home when ecryptfs-setup-private is not installed will yield a meaningful error message and exit non-zero before half-adding a user to the system.

I've retested and this seems to work much better. Thanks for the suggestion and the careful review!

Cheers,
