Subject: Re: Compaq mount patch broken

Yesterday I wrote how using the patched /sbin/mount in

  T64V51B19-C0136901-15143-ES-20020817.tar

killed a running mountd with "User defined signal 1". I reported this to
Compaq support, and within 24 hours they had the solution:

The PK5/BL19 megapatch (t64v51b19as0005-20020411.tar, that I had not
installed) provides a replacement mountd of the "right" version. This
problem was caused by me attempting to install the latest security patch
"by hand", without the required megapatch.
