Some history first: When sys-fs/udisks and sys-power/upower was introduced to Portage, they only had handful of consumers, and there was no sys-apps/systemd in Portage They were non problematic packages and could be considered as wrappers that linked desktops to udev -related functionality But, now, upower upstream writes code only with systemd in mind, dropped hibernate/suspend without any consideration to non-systemd users And, Portage doesn't understand || ( ) dependencies anymore wrt http://bugs.gentoo.org/show_bug.cgi?id=515230 And, people started using local USE flags "udisks" and "upower" despite being advised against it And, more people are requesting sys-fs/udisks and sys-power/upower to be moved away from USE="udev" to these 2 separate flags, like http://bugs.gentoo.org/show_bug.cgi?id=516380 These 2 flags are already enabled by default in the desktop profile target, just like USE="udev" is
So, I propose: upower with short generic description of "Support for power management" udisks with short generic description of "Support for storage management" These packages use them already, but a lot more will follow: [+ D ] upower kde-base/kdelibs: Use upower for power management [+ B] (4/4.12) 4.12.5 [gentoo] [+ B] (4/4.13) 4.13.0 [gentoo] [+ D ] upower kde-misc/synaptiks: Handle mouse devices correctly across suspend and resume with upower [+ B] (4) 0.8.1-r2 [gentoo] [+ B] (4) 0.8.1-r4 [gentoo] [+ D ] upower lxde-base/lxsession: Pull in sys-power/upower for hibernate/suspend support [+ ] 0.4.6.1 [gentoo] [+ ] 0.4.9.2 [gentoo] [+ ] 0.4.9.2-r1 [gentoo] [+ ] 0.4.9.2-r2 [gentoo] [+ ] 0.4.9.2-r3 [gentoo] [+ D ] upower net-im/telepathy-mission-control: Use sys-power/upower to detect suspend and resume [+ B] 5.14.0-r1 [gentoo] [+ B] 5.14.1 [gentoo] 5.16.1 [gentoo] [+ D ] udisks app-emulation/wine: Support dynamic storage devices using sys-fs/udisks 1.2.3 [gentoo] 1.3.28 [gentoo] [+ ] 1.4 [gentoo] [+ ] 1.4.1 [gentoo] [+ ] 1.5.0 [gentoo] [+ ] 1.5.1 [gentoo] [+ ] 1.5.2 [gentoo] [+ ] 1.5.3 [gentoo] [+ ] 1.5.4 [gentoo] [+ ] 1.5.5 [gentoo] [+ ] 1.5.6 [gentoo] [+ ] 1.5.7 [gentoo] [+ ] 1.5.8 [gentoo] [+ ] 1.5.9 [gentoo] [+ ] 1.5.10-r1 [gentoo] [+ ] 1.5.11-r1 [gentoo] [+ ] 1.5.12-r1 [gentoo] [+ ] 1.5.13-r1 [gentoo] [+ ] 1.5.14-r1 [gentoo] [+ ] 1.5.15-r2 [gentoo] [+ ] 1.5.16-r1 [gentoo] [+ ] 1.5.17 [gentoo] [+ ] 1.5.18 [gentoo] [+ ] 1.5.19 [gentoo] [+ ] 1.5.20 [gentoo] [+ ] 1.5.21 [gentoo] [+ ] 1.5.22 [gentoo] [+ ] 1.5.23-r1 [gentoo] [+ ] 1.5.24 [gentoo] [+ ] 1.5.25 [gentoo] [+ ] 1.5.26 [gentoo] [+ ] 1.5.27 [gentoo] [+ ] 1.5.28 [gentoo] [+ ] 1.5.29 [gentoo] [+ ] 1.5.30 [gentoo] [+ ] 1.5.31 [gentoo] [+ B] 1.6 [gentoo] [+ B] 1.6.1 [gentoo] [+ B] 1.6.2 [gentoo] [+ B] 1.7.0 [gentoo] [+ B] 1.7.3 [gentoo] [+ B] 1.7.4 [gentoo] [+ B] 1.7.8 [gentoo] [+ B] 1.7.9 [gentoo] [+ B] 1.7.10 [gentoo] [+ B] 1.7.11 [gentoo] [+ B] 1.7.12 [gentoo] [+ B] 1.7.13 [gentoo] [+ B] 1.7.14 [gentoo] [+ B] 1.7.15 [gentoo] [+ B] 1.7.16 [gentoo] [+ B] 1.7.17 [gentoo] [+ B] 1.7.18 [gentoo] [+ B] 9999 [gentoo] [+ D ] udisks app-leechcraft/lc-vrooby: Use sys-fs/udisks:0 for block device access (e.g., automounting) [+ ] 0.6.60 [gentoo] [+ ] 0.6.65 [gentoo] [+ ] 9999 [gentoo] [+ D ] udisks app-text/calibre: Add run-time dependency on sys-fs/udisks in order to mount and unmount reading devices.
