This was released as test at the start of September, reiterated at the end
of September on this list, then promoted to current stable and announced
early October:
Planning for the future, could the grep package provide egrep and fgrep
in /etc/alternatives? Then a new (optional) package, say "grepfe" could
provide /etc/alternative shell scripts (or binaries) which called
grep -F and grep -E.
Suggest that I could come up with a package grep-nowarn which can only suppress
the [ef]grep warnings, where the package would install [ef]grep-nowarn, and the
postinstall script could rename the distributed shell scripts to [ef]grep-warn,
and install alternatives with -warn priority 10, -nowarn priority 20; preremove
would reverse the process.
Suggestions to accommodate -nowarn from grep package postinstall?
I could supply the same postinstall and preremove as -nowarn to check for
-nowarn and install or uninstall the alternative.
Sequence or timing issues to watch out for during postinstall/preremove?
