[gentoo-dev] Undocumented and unused USE variables
Hello. Currently I am doing a from scratch installation of gentoo. While setting up my USE flags I noticed, that some default USE flags in the default environment (default/linux/amd64/10.0/desktop/kde) are neither documented (in /usr/portage/profiles/use.desc) nor used in IUSE by any package (amd64). I am wondering if they are a leftover from older/outdated packages and could be removed. Here is the list of USE flags I identified at my system: * Undocumented use flags: -- amd64 consolekit declarative gdu kipi mudflap nptlonly pango phonon pppd qt3support sysfs xorg * Unused and undocumented USE flags: -- amd64 mudflap sysfs For those who want to search on their system I attached two scripts: * find_undocumented_uses.sh : searches for use flags which are active but not documenten in /usr/portage/profiles/use.desc. * find_unused_uses.sh : Checks for given USE flags if they are found in any ebuild's IUSE statment find_undocumented_uses.sh Description: application/shellscript find_unused_uses.sh Description: application/shellscript
Re: [gentoo-dev] Undocumented and unused USE variables
Hello. I see. There is more documentation on a per package bases wich has to be considered, too. (Found already the metadata.xml files.) As with the pango USE they may differe in their description - maybe also in their meaning for different packages. So local USE flags should only be used on a per package basis! Here the euse command is realy handy. :-) However the sysfs USE flag is still hiding its documentation. So lets see if this is a bug or a feature. ;-) Thx for the clarification so far.
