29=item I don't like the new selection/popups/hotkeys/perl, how do I
30change/disable it?
31
32You can disable the perl extension completely by setting the
33B<perl-ext-common> resource to the empty string, which also keeps
34rxvt-unicode from initialising perl, saving memory.
35
36If you only want to disable specific features, you first have to
37identify which perl extension is responsible. For this, read the section
38B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
39example, to disable the B<selection-popup> and B<option-popup>, specify
40this B<perl-ext-common> resource:
41
42 URxvt.perl-ext-common: default,-selection-popup,-option-popup
43
44This will keep the default extensions, but disable the two popup
45extensions. Some extensions can also be configured, for example,
46scrollback search mode is triggered by B<M-s>. You can move it to any
47other combination either by setting the B<searchable-scrollback> resource:
48
49 URxvt.searchable-scrollback: CM-s

158
159=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
160
161You should build one binary with the default options. F<configure>
162now enables most useful options, and the trend goes to making them
163runtime-switchable, too, so there is usually no drawback to enbaling them,
164except higher disk and possibly memory usage. The perl interpreter should
165be enabled, as important functionality (menus, selection, likely more in
166the future) depends on it.
167
168You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
169system-wide (except maybe with C<defaults>). This will result in useful
170behaviour. If your distribution aims at low memory, add an empty
171C<perl-ext-common> resource to the app-defaults file. This will keep the
172perl interpreter disabled until the user enables it.
173
174If you can/want build more binaries, I recommend building a minimal
175one with C<--disable-everything> (very useful) and a maximal one with
176C<--enable-everything> (less useful, it will be very big due to a lot of
177encodings built-in that increase download times and are rarely used).
178
179=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
180
181Likely not. While I honestly try to make it secure, and am probably not
182bad at it, I think it is simply unreasonable to expect all of freetype
183+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
184secure. Also, rxvt-unicode disables some options when it detects that it
185runs setuid or setgid, which is not nice. Besides, with the embedded perl
186interpreter the possibility for security problems easily multiplies.
187
188Elevated privileges are only required for utmp and pty operations on some
189systems (for example, GNU/Linux doesn't need any extra privileges for
190ptys, but some need it for utmp support). It is planned to mvoe this into
191a forked handler process, but this is not yet done.
192
193So, while setuid/setgid operation is supported and not a problem on your
194typical single-user-no-other-logins unix desktop, always remember that
195its an awful lot of code, most of which isn't checked for security issues
196regularly.
