Thanks for the hint Stefan! I wanted to use such "DEPENDS" type instead of "define (...)/config" block but unfortunately after converting "Kconfig selects" to equivalent "openwrt DEPENDS:", eg: *DEPENDS:=+@!PACKAGE_swap-utils:BUSYBOX_CONFIG_MKSWAP +@!PACKAGE_swap-utils:BUSYBOX_CONFIG_SWAPONOFF* I got this in opkg control file: *Package: kmod-zram Version: 3.6.11-1 Depends: kernel (=3.6.11-1-479d5850a6a04abbd6713ee6c4ef65ac), kmod-lib-lzo, kmod-zsmalloc, **BUSYBOX_CONFIG_MKSWAP, **BUSYBOX_CONFIG_SWAPONOFF, * This doesn't look good, does it? So I tried to reverse this dependency to allow people using buildroot to have the possibility to optimize their builds and be able to select busybox applets instead of swap-utils package, and also leaving other people using prebuild images the possibility to install this kmod package through opkg with appropriate dependencies. Unfortunately with this: *DEPENDS:=+@!BUSYBOX_CONFIG_MKSWAP:PACKAGE_swap-utils +@!BUSYBOX_CONFIG_SWAPONOFF:PACKAGE_swap-utils* I got this in opkg control file: *Package: kmod-zram Version: 3.6.11-1 Depends: kernel (=3.6.11-1-479d5850a6a04abbd6713ee6c4ef65ac), kmod-lib-lzo, kmod-zsmalloc, PACKAGE_swap-utils, PACKAGE_swap-utils * Which still doesn't look good. @devs: Is there any chance for patch to opkg system so it generates proper "Depends:" in such situations? I mean "swap-utils" instead of " PACKAGE_swap-utils" This would be useful I think. What do you think? btw. shouldn't we move init script to some seperate userspace package and put the dependencies there? zram doesn't need swap-utils ... what if one want to use it for some other stuff. I know that init script is not much for a seperate package... but... is it a good idea to put some init script in kernel module package? btw2. This also doesn't work: *DEPENDS:=+@!BUSYBOX_CONFIG_MKSWAP:swap-utils +@!BUSYBOX_CONFIG_SWAPONOFF:swap-utils*
