To illustrate:
On my box without this patch: dmsetup version Library version: 1.02.42 (2010-01-14) /proc/misc: No entry for device-mapper found Is device-mapper driver missing from kernel? Failure to communicate with kernel device-mapper driver.
And the same box just with this patch, nothing else changed: dmsetup version Library version: 1.02.42 (2010-01-14) Driver version: 4.17.0
But its up to you to care if device-mapper just works, or if there is stuff like an init script with modprobe needed to load stuff that might never be needed. :)
This is surely not about dynamic vs. static, it is about race-free on-demand activation of services and subsystems.
Thanks, Kay
