And as I said I know that you *can* run out of disk space and effectively break your OpenWRT installation. As you can do with your mentioned 'dd if=/dev/zero of=/fill.bin' or with 'opkg upgrade `opkg list-upgradable | sed 's|\ .*||'`' You can also break your router in plenty of other ways. But dd is still in. I also know people are dumb and will do it, but they are also creative and can use google so they will do it anyway (and when I google for opkg upgrade, workarounds to get opkg upgrade all back is the 3rd to 8th link showed on the results page). So from the replies so far I guess the only reason for disabling it is the try to prevent people from doing stupid stuff, nothing really broken, right? > Regards, > > Daniel > > > > >>Em qua, 30 de mar de 2016 02:30, Michal Hrusecky <michal.hruse...@nic.cz> > >>escreveu: > >> > >>>Luiz Angelo Daros de Luca - 1:41 30.03.16 wrote: > >>>>Michal, > >>>> > >>>>Google is your friend ;-) > >>> > >>>He pretends he is, but didn't provided the answer I was looking for, just > >>>plenty of workarounds I mentioned ;-) > >>> > >>>>But I'll easy your search > >>>>https://wiki.openwrt.org/doc/techref/opkg > >>>> > >>>>Check the upgrade description. > >>> > >>>Reread and the only thing that is mentioned there is general discourage to > >>>do > >>>upgrades and be careful what you are doing and that there are generally no > >>>updates available apart from trunk and that opkg will not upgrade kernel. > >>>No > >>>technical problem and no specific issue with upgrade all. > >>> > >>>>Regards > >>>> > >>>>Em ter, 29 de mar de 2016 às 04:45, Michal Hrusecky < > >>>michal.hruse...@nic.cz> > >>>>escreveu: > >>>> > >>>>>Hi, > >>>>> > >>>>>there is a patch in OpenWRT that disables option to upgrade all > >>>packages > >>>>>and > >>>>>allows upgrading only specified packages which leads to plenty of > >>>answers > >>>>>online how to do that[1][2][3][...] Does anybody remembers the reason > >>>for > >>>>>disabling it?
