IMHO it would be both easier and faster to deploy a proper migration plan and keep going. Nobody said the names used by X.org keysyms have to agree with the ones used by input devices, for example... and a mapping table is already used anyway. So, userspace can use the X keysyms like the above. There's nothing wrong with it. But the correct mapping for kernel input events to those keysyms is AND WILL REMAIN: KEY_SLEEP -> XF86XK_Suspend KEY_SUSPEND -> XF86XK_Hibernate If people want to define two new input events, say KEY_SUSPENDTORAM and KEY_SUSPENDTODISK, start migrating the kernel drivers to use these two, and after some time with no use of KEY_SLEEP in the kernel, reclaim it to be a generic "sleep the system in some unspecified way", I'd be fine with it. So, you'd have: KEY_SLEEP -> XF86XK_Suspend KEY_SUSPENDTORAM -> XF86XK_Suspend KEY_SUSPEND -> XF86XK_Hibernate KEY_SUSPENDTODISK -> XF86XK_Hibernate I'd guess the only thing that could make us break that ABI the way people wanted us to (i.e. change the meaning of KEY_SUSPEND and KEY_SLEEP, and add a new KEY_HIBERNATE), is a proof that we got the USB HID table wrong and that USB keyboards are doing the wrong thing because of it. -- "One disk to rule them all, One disk to find them.
