I noticed that RBM continuously calls `lsb_release -irc`. Currently, `lsb_release` calls `apt-cache` on my Debian system, and it fills `/var/cache/apt` with temporary `pkgcache.bin` and `srcpkgcache.bin` and does not delete them. Of course, this is Debian's bug (I will verify if one exists, or open one in case), but it is still a problem for us: a `lsb_release -irc` call takes almost a second, and it is called a crazy high number of times! ``` time lsb_release -irc Distributor ID: Debian Release: testing/unstable Codename: n/a ________________________________________________________ Executed in 908.69 millis fish external usr time 841.37 millis 336.00 micros 841.03 millis sys time 67.85 millis 0.00 micros 67.85 millis ``` Therefore, my proposal is to cache this value.
