Apart from the FEATURE_SYSTEMD discussed above, these are the other new options that I kept the new busybox default on (i.e. these are enabled, while I turned of quite a few other options that automatically got enabled). All costs are evaluted using qemux86, and the busybox binary size is checked in the packages-split/busybox/bin directory. I don't mind disabling any of these feature in a v3, if desired/requested. Anyway, I'm running a completely custom config for my normal uses... FEATURE_RTMINMAX, support RTMIN[+n] RTMAX[-n] signals, claimed to cost ~250 bytes FEATURE_REVERSE_SEARCH claimed to cost ~0.5k FEATURE_SKIP_ROOTFS ignore rootfs entry in mount table (tools like df etc will ignore it). FEATURE_AR_CREATE, enable ar to create files, ~2.5k FEATURE_SEAMLESS_XZ enable xz compression in tar, no measured cost. XZ and UNXZ, enable xz compression, 8k FGCONSOLE, print active console number, 128 bytes FEATURE_LOADFONT_PSF2, FEATURE_LOADFONT_RAW, cost 576 bytes FEATURE_VI_ASK_TERMINAL, last resort to find terminal size, 352 bytes BLOCKDEV, perform some ioctls with block devices, cost 480 bytes FDISK_SUPPORT_LARGE_DISKS, is disabled, it no longer wants to play with LFS (both were enabled previously). FEATURE_MOUNT_LOOP_CREATE, create new loopback devices if needed, couldn't see any cost FEATURE_WGET_TIMEOUT, no visible cost FEATURE_SH_HISTFILESIZE, use $HISTFILESIZE (still max limited by config), no visible cost FEATURE_SYSLOGD_CFG, support syslog.conf, no visible cost FEATURE_SYSLOGD_READ_BUFFER_SIZE, defines the size of the read buffer, not measured FEATURE_KLOGD_KLOGCTL, let klogd use the klogctl() interface, no visible cost Cheers, Anders -- Anders Darander ChargeStorm AB / eStorm AB _______________________________________________ Openembedded-core mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
