The same strategy applies to the non-suid apps.
Hi, have you tried to do on-device upgrade with this change? It looks very broken, description follows: 13:48:33 < JaMa> was sed applet removed from busybox or something like that? upgrade path seems to be broken 13:48:34 < JaMa> Configuring busybox-syslog. 13:48:34 < JaMa> /usr/bin/update-alternatives: line 186: sed: not found 13:48:58 < JaMa> and then all applets in main busybox package fail to set u-a because of missing sed.. 13:49:27 < JaMa> and then fixing that is more complicated because wget symlink is gone too, so opkg update opkg upgrade wont work 13:49:40 < zecke> JaMa: IIRC the specific postinst was removed from busybox?! 13:50:55 < JaMa> /var/lib/opkg/info/busybox.postinst is still there 13:51:02 < JaMa> with a lot of u-a calls 13:51:34 < zecke> JaMa: generated by the bbclass and not the one that was in the busybox.inc (but i only read the digest and skip stuff) 13:51:37 < JaMa> that commit says it removes redundant u-a 13:52:11 < JaMa> SHR root@gjama ~ $ grep sed /var/lib/opkg/info/busybox.postinst update-alternatives --install /bin/sed sed /bin/busybox.nosuid 50 13:52:23 < zecke> JaMa: Do you know if they/he tested on device upgrade? 13:52:56 < zecke> i am obviously just guessing 13:54:05 < JaMa> all u-a are still pointing to /bin/busybox, but that one is gone replaced by /bin/busybox.(no)suid 13:54:44 < JaMa> we should install /bin/busybox -> /bin/busybox.nosuid to fix upgrade path..
