Hi, sourcing a script with 'dot' doesn't set the positional parameters,
see http://www.opengroup.org/onlinepubs/009695399/utilities/dot.html,
so when doing '. ./postrm purge', $1 will not necessarily be 'purge'.
If not, the script simply exits 0 because the first condition in not
met.
I not yet see the serious bug in dash.
Regards, Gerrit.
