uncompression and file installation
Maybe, but somewhat should first take a look where all the time is spent in
the rpm installation code. Maybe uncompression is just 10% and file system
operation is 70%. Or the other way round. Or maybe it's the fsync() on
It is the dracut initrd regeneration for me actually, even on SSD it takes *minutes* :).
That's a long-standing pain, yeah. Did anyone profile the dracut
operation to point out what takes so long? I know xz takes quite some
time, but it's not dominant, I guess.
