84 /* XXX: DPKG_INCOMPATIBILITY: deb_extract will extract all of the
85 data file names with a '.' as the first character. I've taught
86 opkg how to cope with the presence or absence of the '.', but
87 this may trip up dpkg.
89 For all I know, this could actually be a bug in opkg-build. So,
90 I'll have to try installing some .debs and comparing the *.list
93 If we wanted to, we could workaround the deb_extract behavior
94 right here, by writing to a tmpfile, then munging things as we
95 wrote to the actual stream. */
