Subject: sys: packagelist: drop ABI version from package name
X-Git-Url: http://git.openwrt.org/%22https:/collectd.org//%22/%22https:/collectd.org/%22?a=commitdiff_plain;h=ccb75178cf6a726896729c6904bd623636aa0b29;p=project%2Frpcd.git

sys: packagelist: drop ABI version from package name

Having the ABI version appended to the package name is not very helpful
when checking for updated versions of a package online or requesting
a new image for the device from an updater service. In both cases,
the ABI version could have been bumped meanwhile and that name is then
simply not found.
Resolve this by removing the appended ABI version in the output of the
rpc-sys packagelist call.
